I've seen this elsewhere. You have a time machine, not sure how you got it, it's just there and you don't ask questions. You see a note "Travel back in time and punch ____ in the face.". Who are you fighting and why? Hitler, Pol Pot, the truly evil guys are taken. The previous time travelers have taken care of them. Find someone you think you could take and let us know who it is. http://en.wikipedia.org/wiki/Thomas_Edison I just want to take him down a peg.
