Favorite X-Man? Wolverine, obviously. When he gets pissed, he kills people. I mean, you can't really beat that for a comic book hero. One time he was all like "Snickt!" and the dude was all like "Arrghh!" and he chops this dude in half and I was like all "OMG! That is fucking awesome!"
So really this should be "Who is your second-favorite X-Man?" I guess I would still have to say Wolverine. But technically that's still Wolverine, so I will say Wolverine's penis.
