&lt;div&gt;{{comic&lt;br /&gt;
| number    = 468&lt;br /&gt;
| date      = 2008-08-27&lt;br /&gt;
| title     = Fetishes&lt;br /&gt;
| image     = fetishes.png&lt;br /&gt;
| titletext = They eventually resolved this self-reference, but Cantor&amp;amp;#39;s &amp;amp;#39;everything-in-the-fetish-book-twice&amp;amp;#39; parties finally sunk the idea.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Bertrand Russell and Alfred North Whitehead co-wrote the ''Principia Mathematica'', with the intention of cataloging all of mathematics and ridding it of contradiction and self-reference. Kurt Gödel later showed that such a system is impossible, and that any system of axioms (like mathematics) is incomplete.&lt;br /&gt;
&lt;br /&gt;
Here, Russel and Whitehead are perusing a more salacious, but no less comprehensive, task: compiling a list of all sexual fetishes. When Gödel says he likes &amp;quot;anything not on your list,&amp;quot; Russel and Whitehead have no way to complete their list. Whatever they leave off should be on the list, as long as it's off the list. This paradox is essentially the same as the one that doomed the ''Principia''.&lt;br /&gt;
&lt;br /&gt;
In the title text, Georg Cantor is the inventor of set theory. If you have a fetish for doing everything in the book twice, than that belongs in the book, which you then have to do once more, which adds another item to the book ''ad infinitum''. Russel and Whitehead finally acknowledge their defeat.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:Author Katherine Gates recently attempted&lt;br /&gt;
:to make a chart of all sexual fetishes.&lt;br /&gt;
&lt;br /&gt;
:Little did she know that Russel and Whitehead&lt;br /&gt;
:had already failed at this same task.&lt;br /&gt;
&lt;br /&gt;
:[Russel and Whitehead are standing with Gödel, Russel holding a clipboard and smoking a pipe.]&lt;br /&gt;
&lt;br /&gt;
:Russel: Hey, Gödel — we&amp;amp;#39;re compiling&lt;br /&gt;
:a comprehensive list of fetishes.&lt;br /&gt;
:What turns you on?&lt;br /&gt;
&lt;br /&gt;
:Gödel: Anything not&lt;br /&gt;
:on your list.&lt;br /&gt;
&lt;br /&gt;
:Russel: Uh…hm.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 514&lt;br /&gt;
| date      = 2008-12-08&lt;br /&gt;
| title     = Simultaneous&lt;br /&gt;
| image     = simultaneous.png&lt;br /&gt;
| titletext = I&amp;amp;#39;m leaving you for your twin.  He&amp;amp;#39;s more mature than you by now.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Cueball and Cutie are talking about the sex they just had. Cueball is remarking on how they both achieved orgasm simultaneously, but Cutie disagrees.&lt;br /&gt;
&lt;br /&gt;
This comic is a play on Einstein's Theory of Special Relativity. One piece of the theory deals with two observers, neither of whom are accelerating but one of whom is moving at close to the speed of light compared to the other. According to Einstein, events that appear simultaneous to one observer will appear to happen at different times to the other.&lt;br /&gt;
&lt;br /&gt;
So when one partner is moving and the other isn't, it's possible that they experience their orgasm at different times relative to each other. That would require one partner to be moving really fast in one direction, which would make him or her either a really bad partner, or a really good one.&lt;br /&gt;
&lt;br /&gt;
The title text is reference to the twin paradox, which arises from another piece of Special Relativity. In theory, if you stick one twin on a spaceship at near lightspeed and keep the other back on earth, the former will only experience a few years while the latter will age decades. Cutie (or Cueball if he rolls that way) expresses a preference for the older twin, who will be more &amp;quot;mature&amp;quot;, meaning both older and less combative about simultaneity.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball and Cutie in bed.]&lt;br /&gt;
:Cueball: &amp;amp;quot;Mmm, simultaneous orgasms&amp;amp;quot;&lt;br /&gt;
:Cutie: &amp;amp;quot;That wasn&amp;amp;#39;t simultaneous&amp;amp;quot;&lt;br /&gt;
:Cueball: &amp;amp;quot;Huh?  It totally was!&amp;amp;quot;&lt;br /&gt;
:A common disagreement when one of you is doing all the moving&lt;br /&gt;
