Because I didn't know: https://en.wikipedia.org/wiki/Ballistic:_Ecks_vs._Sever - &amp;quot;Ballistic: Ecks vs. Sever is a 2002 action thriller film directed by Wych Kaosayananda (under the pseudonym of &amp;quot;Kaos&amp;quot;). The film stars Antonio Banderas and Lucy Liu as opposing secret agents who team up to fight a common enemy. It is an international co-production between Canada, Germany and the United States.&lt;br /&gt;
The film has been called one of the worst ever made. At the box office, it made $19.9 million on a $70 million budget. With a total of 117 reviews, the highest for a film with a 0% score, Ballistic: Ecks vs. Sever is the worst reviewed film in the history of Rotten Tomatoes.&amp;quot; [[User:Afbach|Afbach]] ([[User talk:Afbach|talk]])&lt;br /&gt;

Re: King Kong vs Godzilla - the winner? WikiP notes: &amp;quot;After an underwater battle (off-screen) only Kong resurfaces from the water, and he begins to swim back towards his island home. There is no sign of Godzilla, but the JSDF speculates that it is possible that it survived.&amp;quot; We never see another K.K. movie (from Japan, anyway) and plenty more Godzilla so maybe K.K. is just swimming home with his tail between his legs ... er, metaphorically speaking.

Some of these matchups have relatively clear outcomes, e.g. Ford beat Ferrari (at least in the movie), and presumably we can say Kramer won Kramer v. Kramer (well, everybody lost, but...). That in mind, if we fill out the bracket with such nominal wins that lead to matchups, (Kramer v. Ford), do we learn anything interesting? And what does the resulting bracket look like?

Joe does not defeat the volcano.  Joe is supposed to throw himself into the volcano as a sacrifice, thus stopping the volcano from accomplishing it's presumed goal of destroying the island.  But Joe is blown out of the volcano (and out of any applicable laws of physics) and the volcano does destroy the island.  So, clearly, the volcano was victorious.  Joe survived the encounter, but did not accomplish the stated goal of the match-up.  Give the bracket to the volcano. --[[User:Suttkus|Suttkus]] ([[User talk:Suttkus|talk]]) 02:46, 19 November 2019 (UTC)&lt;/div&gt;</summary>

Why are we assuming there are any side effects like these? The pendulum stops the Earth from rotating -- couldn't this include the entire planet, including the atmosphere and loose objects such as humans? There probably would be some volcanoes from the sudden loss of centrifugal force, though. [[Special:Contributions/162.158.39.23|162.158.39.23]] 13:52, 13 September 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I take it the pendulum is somewhere deep underground, which would shield Black Hat from the cataclysmic side effects?&lt;br /&gt;
Besides, they have several backup pendulums that while not enough to maintain rotation are sufficient to slow the half enough to preserve life.[[Special:Contributions/108.162.212.149|108.162.212.149]] 20:11, 11 September 2019 (UTC)&lt;br /&gt;
:I fear that the use of multiple pendulums to smooth out the catastrophy of stoping the Earth's rotation would probably just cause bits of the Earth to keep going and other bits to stop. Hey! That's plate techtonics! ''Obviously'' there are subtly dampened/purturbed pendula in secret (masonic?) temples all across the world, making all that happen! Someone likely pushed the one in Atlantis too far, one fateful day...&lt;br /&gt;
:(BTW, the unsaid catastrophe element reminds me of a classic [https://en.wikipedia.org/wiki/The_Man_Who_Could_Work_Miracles_(story) short story])[[Special:Contributions/162.158.154.31|162.158.154.31]] 15:29, 12 September 2019 (UTC)&lt;br /&gt;
::These effects will of course not work on Black Hat or any other that are at the Eart Rotation controlling Pendulum at The South Pole observatory. There the Earth stopping will not have any effect :-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:53, 13 September 2019 (UTC)&lt;br /&gt;
:::Well, maybe a bit of nanodiziness..? [[Special:Contributions/162.158.158.209|162.158.158.209]] 16:17, 16 September 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
If the pendulum could really affect Earth's rotation, Black Hat wouldn't need to stop the pendulum entirely; he'd only need to prevent its plane of oscillation from rotating. Another thought: if the pendulum and Earth's rotation were really bidirectionally linked somehow, there would probably be nothing Black Hat could do to alter the pendulum's plane of oscillation -- any more than he could alter the rotation of the Earth with just one human being's strength. That last thought doesn't seem to be the case within this story, though, or else the final frame's news report wouldn't have happened. [[User:Trueflint|Trueflint]] ([[User talk:Trueflint|talk]]) 20:46, 11 September 2019 (UTC)&lt;br /&gt;
:Who says it's the energy from Black Hat's grab specifically? Maybe the magic pendulum just tells a device in the Earth whether or not the planet should be spinning, based on the current state of the pendulum.

Why does the description description Megan as a &amp;quot;professor?&amp;quot; She could just as easily be a teacher, a docent, a scientifically-interested parent, or just a random bystander. 11 September 2019&lt;br /&gt;
:Agree this is more like a tour guide if anything. I will correct this. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:51, 13 September 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
The sentence &amp;quot;It stays in a fixed plane while the Earth rotates under it.&amp;quot; and the correspoding text in explanation are wrong. It would be true only if the pendulum was located on one of Earth's poles. Elsewhere, the plane in which the pendulum moves would still rotate with respect to its surrondings, but slower than on the pole. The rotation speed is proportional to the sine of latitude. At the equator, the plane would stay fixed with respect to its surroundings. See [https://en.wikipedia.org/wiki/Foucault_pendulum#Explanation_of_mechanics Wikipedia].--[[Special:Contributions/162.158.93.207|162.158.93.207]] 23:45, 11 September 2019 (UTC)&lt;br /&gt;
:As a Physics teacher, I strongly support this. The fact that a Foucault's pendulum is keeping its oscillation plane constant with respect to an absolute reference frame is a common misconception, it should be mentionned as frequently as possible.--[[Special:Contributions/108.162.229.48|108.162.229.48]] 09:17, 12 September 2019 (UTC)&lt;br /&gt;

&lt;br /&gt;
The Foucault Pendulum in this comic strongly resembles the one in the Franklin Institute in Philadelphia  (both in shape and the way it is knocking over the pegs).  Perhaps this should also be noted in the trivia section?[[Special:Contributions/162.158.126.46|162.158.126.46]] 05:16, 12 September 2019 (UTC)&lt;br /&gt;

::A Google search reveals that nearly all of them have a weight that looks like the one in this comic, and many of them have some sort of pegs to demonstrate the circular motion over the course of a day. To put the location of any of them in the explanation (as it is now) is probably not appropriate.  If there is a significant one somewhere in the world (largest, oldest, etc), then maybe we could mention that specific one.

&lt;br /&gt;
I don't think there's any indication that this comic takes place during a physics lecture. It's more likely that it takes place in a science museum, and this is a museum tour guide explaining the Foucault Pendulum to museum visitors.

I don't know if it's still the case, but back in the 90s some Earth orientation work was very hush-hush military business.

You really do not want to mess with IERRSS (IRS for short). Also, the pendulum is in an inertial reference frame to what?

*Are* costumes well-ordered?  Even leaving aside the subjectivity of any ranking, there are several different criteria which could be used, and many ways of combining them.  (What if the costume which looked least like Marty wasn't the ugliest, nor the one showing least effort?)  — Also, may be worth qualifying the explanation of Halloween by mentioning the USA; some other countries don't celebrate it, and of those that do, not all do trick-or-treating or dressing-up &amp;amp;c.

::Saying there are different criteria kind of overlaps with saying the ranking is subjective. But far worse, even individual preferences are preorders aka quasiorders, which absolutely does mean that there may not be a worst, or even a set of costumes tied for worst. However, the fact that you can always find someone (e.g. on Amazon Mechanical Turk, or off the street, or on a wiki somewhere) to give you another opinion means that well-foundedness can be rescued with their {{w|mean opinion score}}. I wonder if the genie is powerful enough to know the asymptotic MOS ranking right away, or if it will have to wait for enough Amazon Mechanical Turk HITs to be completed.

Even if &amp;quot;preference&amp;quot; is a total order (i.e. connex and anti-symmetric, I think both of these are debatable) it isn't necessarily a well order, however, since the set of costumes is finite, there would still be a &amp;quot;worst&amp;quot; one.

:It's not a total preorder unless you don't let people have &amp;quot;no opinion&amp;quot; about some pairs, which is an acceptable constraint for preferences based on established objective criteria, but not something so subjective like quality of fashion. In practice, a lot of people are going to have least favorites between which they don't care. Surveys of subjective preferences almost always allow people to say that they don't have opinions or are not sure. Even in technically objective measures, like short- versus long-term bond yield curves, you can sometimes prove that people objectively should have certain preferences upon which they are clearly not acting.

Still a &amp;quot;trap&amp;quot;: POOF, you're now the worst McFly cosplayer; here's a mirror.&lt;br /&gt;
:She asked about people who 'tried' to dress as Marty McFly. So unless Megan has ever tried to dress as him, I don't think she can be the answer.[[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 00:10, 24 August 2019 (UTC)&lt;br /&gt;
::_Technically_, Megan never used the formal &amp;quot;I wish&amp;quot; construction: she had &amp;quot;my wish is&amp;quot; and &amp;quot;just show me.&amp;quot; Since the genie didn't immediately grant it in response to &amp;quot;my wish is,&amp;quot; either (1) it's not possible (see other folks' comments below), (2) like Alex Trebec, he requires the proper format, or (3) we can assume that he'll respond to a direct order ... in which case, Megan will become a McFly cosplayer in a subsequent panel. :p&lt;br /&gt;
:Considering that wishing for any of the genie's suggestions would make her a wanted criminal that stole a billion dollars, a housefly in a room full of irritable people, or a genie trapped in a lamp for all eternity, this is hardly a terrible fate.

&lt;br /&gt;
: Beware.  The worst Marty McFly may be truly terrible.  Or it could be a little kid in a costume they made out of craft paper and colored in crayon, terrible but adorable...  but it could involve (1) real lightning, (2) real plutonium, (3) the band McFly, (4) actually a dog in costume, (5) actually a fly in costume, (6) Jeff Goldblum from &amp;quot;The Fly&amp;quot; i.e. fly head not Jeff Goldblum head - in costume, (7) Cthulhu - in costume.  (The last and worst trick-or-treat you'll ever see; he would qualify.)  rja.carnegie@gmail.com [[Special:Contributions/162.158.158.209|162.158.158.209]] 14:36, 26 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
*Are* costumes well-ordered?  Even leaving aside the subjectivity of any ranking, there are several different criteria which could be used, and many ways of combining them.  (What if the costume which looked least like Marty wasn't the ugliest, nor the one showing least effort?)  — Also, may be worth qualifying the explanation of Halloween by mentioning the USA; some other countries don't celebrate it, and of those that do, not all do trick-or-treating or dressing-up &amp;amp;c. [[User:Gidds|Gidds]] ([[User talk:Gidds|talk]]) 00:23, 24 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
::Saying there are different criteria kind of overlaps with saying the ranking is subjective. But far worse, even individual preferences are preorders aka quasiorders, which absolutely does mean that there may not be a worst, or even a set of costumes tied for worst. However, the fact that you can always find someone (e.g. on Amazon Mechanical Turk, or off the street, or on a wiki somewhere) to give you another opinion means that well-foundedness can be rescued with their {{w|mean opinion score}}. I wonder if the genie is powerful enough to know the asymptotic MOS ranking right away, or if it will have to wait for enough Amazon Mechanical Turk HITs to be completed. Given that there must have been at least hundreds of thousands of consumes so far, that could take quite a long time to achieve p&amp;lt;0.05.

I don't know to what &amp;quot;Word of Power&amp;quot; in the title text refers. A quick Google revealed something from Skyrim and something from D&amp;amp;D, but I have the feeling there must surely be a more original source for it, even if it is just a common term in folklore or something. [[User:Pureawes0me|Pureawes0me]] ([[User talk:Pureawes0me|talk]]) 07:45, 19 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
: I think it means &amp;quot;magic word&amp;quot;.  The next step, &amp;quot;Unforgivable Curse&amp;quot;, is from Harry Potter; a magic spell against someone that will get you jail time.  (C. S. Lewis had an apocalyptic option, the &amp;quot;{{w|Deplorable Word}}&amp;quot;, which killed every living person except the speaker)  So Harry Potter's schoolteacher demonstrates the Unforgivables on spiders... and on students.  (You find out why.)  Also I think the title text is the platform speaker's response to Beret Guy.  rja.carnegie@gmail.com [[Special:Contributions/162.158.158.183|162.158.158.183]] 09:12, 19 August 2019 (UTC) [[User:WhiteDragon|WhiteDragon]] ([[User talk:WhiteDragon|talk]]) 13:51, 19 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
:: Yeah, I understand the &amp;quot;Unforgivable Curse&amp;quot; part - it's more &amp;quot;Word of Power&amp;quot; I'm struggling with. I agree that the title text could potentially be a response by the speaker, and I've updated the page to reflect this.

::: It's from tabletop roleplaying games; [https://dungeonsdragons.fandom.com/wiki/Power_word some of the earliest high level spells from the original edition of Dungeons and Dragons were &amp;quot;Power Word Kill,&amp;quot; &amp;quot;Power Word Blind,&amp;quot; and &amp;quot;Power Word Stun.&amp;quot;] These spells have been carried forward into newer editions where they are extremely unpopular because they were designed for campaigns when most monsters had a tiny fraction of the number of hit points typical today, and unlike essentially all of the fifth edition spells, they don't do anything when they don't work, and they don't work based on facts which are theoretically unknowable to the players. So, they kind of have a reputation of the worst high level spells, and are sometimes included in magic items which turn out to be, well, like fruitcake, if you know what I mean.

&lt;br /&gt;
:::: Re-reading, incantation already is a magic spell, probably.  In current use, malediction can be either speaking against someone or something, or its original meaning of actual malicious verbal magic.  So I suppose Word of Power has to be more than a magic word...  I found a couple of references in the world of H. P. Lovecraft but those I traced were 1970s or later, actually after D-and-D.  So, not definite.  rja.carnegie@gmail.com [[Special:Contributions/162.158.158.209|162.158.158.209]] 00:14, 20 August 2019 (UTC)&lt;br /&gt;

One thing I feel needs to be said is that this behavior belies a lack of linguistic skill, because any statement can always be phrased in the form of a question, e.g, most easily, &amp;quot;Do you agree that _______?&amp;quot; Or by asking about the details of the comment about which the commenter is most interested in emphasizing or soliciting a response. That this kind of thing happens among advanced academics belies how narcissistic and tone-deaf even otherwise intelligent people can often be.

:Similar to how the comic ends in a question? I think your statement is part of the joke. Less of a statement, and more of an utterance. [[User:OhFFS|OhFFS]] ([[User talk:OhFFS|talk]]) 14:28, 19 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
There is a Russian Folk Tale, among those collected by Afanasyev, called &amp;quot;Go I don't know where, Bring back I don't know what&amp;quot;. In that story, the archer Andrey is given several impossible tasks by a tsar who covets his beautiful wife, the last of which is to go to I don't know where and bring back I don't know what.  After journeying a vast distance and meeting his mother in law Baba Yaga, he is guided by an ancient frog across a river of fire, and is told &amp;quot;Over there you will find a house. Well, not so much a house as a hut.  And it is not so much of a hut as a barn.&amp;quot;  This is I don't know where. So Beret Guy's intro to his statement may be a reference to this formulaic format.&lt;br /&gt;
&lt;br /&gt;
: ...his mother in law is Baba Yaga?  Did he know that?  Does the tsar know that?  Does it change matters tsar-and-beautiful-wife-wise...  (Is this story in English at all, I don't know where...)  Wikipedia knows several Baba Yaga stories (some with three Baba Yagas who don't live together, unless this is a complicated alibi) but none match this.  rja.carnegie@gmail.com [[Special:Contributions/162.158.158.209|162.158.158.209]] 00:14, 20 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think the Unforgivable Curse line in the title text is meant to reference the scene in HP&amp;amp;tGoF when Barty Crouch, posing as Professor Moody, demonstrates their use on spiders to the fourth years in Defense Against the Dark Arts. The curse, be it an annoyed audience member or the speaker, is to be cast on the friendly bug. [[Special:Contributions/108.162.238.83|108.162.238.83]] 21:04, 19 August 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I don't think Beret Guy is trying to say that he and the speaker are friends in his last line, I'm pretty sure he's saying that he's friends with the bug he found.&lt;/div&gt;</summary>
