Explain xkcd: It's 'cause you're dumb.
Black Hat creates a one use time machine. Cueball selects the most common suggestion for Time Machine usage: killing Adolf Hitler. Black Hat finally relents and goes to kill Hitler. However, he goes to April 30th, 1945, when Hitler actually committed suicide in reality, therefore not changing any history or avoiding any of the atrocities carried out by Nazi Germany. The title text also refers to the time travel theme from the Superman movie in which Jor-El states: "It is forbidden for you to interfere with human history".
Alternatively, Black Hat really could have killed Hitler in the bunker in 1945, which relates to conspiracies that Hitler was shot by someone other than himself.
- [Black Hat and Cueball stand in front of a double door, which bears the label 'TIME door'. Black Hat has his hands on his hips.]
- Black Hat: I finished my time machine, but it's one-use only.
- Cueball: You gotta kill Hitler.
- [Close-up of Black Hat, one hand palm upward.]
- Black Hat: Why are you so obsessed with this Hitler guy? We have all of time we could explore!
- [Close-up of Cueball with both hands palm upward.]
- Cueball: He's evil incarnate! He murdered millions and sparked global war! Everyone agrees -- if you get a time machine, you kill Hitler.
- [Black Hat enters the now open Time door as the other man looks on..]
- Black Hat: Fine, fine, I get it! Calm down. BRB, killing Hitler.
add a comment!
- [Black Hat returns and shuts the door, the other man has outstretched arms.]
- Black Hat: There. Done. Are you happy?
- Cueball: Thank you.
- Black Hat: He was in some kind of bunker. 1945 was loud!
- Cueball: NO!
Actually, I think the joke here is that Black Hat actually did end Hitler's atrocities, but that history is not actually changeable. Hitler's "suicide" was actually Black Hat killing him. This is then layers with the impossibility of changing history. This would imply that anyone that wants to stop Hitler before he rose to power will be circumvented.

- According to all reasonable time travel theories, this makes sense. You cannot go into the past to change things, because the future that exists is a future where you were in the past - you just didn't know it yet because it was in your future. This also applies to the future. Your knowledge of the future cannot possibly change it because your foreknowledge exists in this future. If your foreknowledge made that future not happen, then there would be no need to change it. But the future and the past account for the fact that you were there to change things, even before you ever knew you would be. Ergo, any attempt to change the past will merely result in causing the past to result exactly as it did before. The catch-22 of time travel stories. You can have a fatal flaw, or a fatally uncompelling story. But, all that said, this is a cartoon and not necessarily reliant on reasonable time travel theory.22.214.171.124 07:07, 23 June 2013 (UTC)
True, killing Hitler before he rose to power and committed all his atrocities would cause a Grandfather paradox... Cueball invented the time machine and send Black Hat back because he wanted Hitler dead, but if Hitler died before that, there would be no reason to invent the time machine and send Black Hat back which ergo cause the initial trip to kill Hitler not possible and ergo Hitler couldn't die before he rises to power and committed his atrocities. 126.96.36.199 01:40, 5 December 2012 (UTC)
Maybe in the original timeline, Hitler's atrocities extended beyond 1945. When Black Hat went back in time and assassinated Hitler in 1945, a new time-line was created. When Black Hat returned to the current date, he returned to a different timeline than the one he left. In this timeline (ours), Hitler died in 1945, and because this timeline is based on that fact, Cueball thinks that Black Hat has not changed anything, when in fact, Black Hat's actions created the new timeline. -- mwburden 188.8.131.52 15:00, 7 December 2012 (UTC)
- The only flaw in that logic is that there's really no way Hitler would have survived the Russian invasion. He was in a bunker, killing himself, because his whole nation and army were crushed. He would have been put on trial and no doubt executed, if not shot by the first soldier who saw him. -HavokTheorem 184.108.40.206 04:30, 9 October 2013 (UTC)
