Let's all hit the bottom of the barrel together with that most braindead of time-passers: stupid hypothetical questions amongst your most retarded of friends strangers.

Read the most recent hypothetical question in this thread. Leave your true and honest answer, followed by a new hypothetical question for some other poor sperg to answer. Try to give specific details to avoid questions of clarification.

I'll begin.

Say you're alone in a room with both Hitler and Stalin, just before the beginning of WWII. You don't know where this room is, it could be anywhere in the world. In front of you is an atomic bomb with a big red button on it that will trigger the bomb and blow up you, Hitler, Stalin and everyone in a 50km radius. In front of you is a green button. If you press this button then you will be returned to present day and history will remain unchanged. Hitler and Stalin are both reaching for their guns, so you have to press a button quickly. Which button do you press and why?
