First, I wipe the vomit off of me. Then, I pull his pants off as well, and kick him in the genitals! Then, I pull my own pants back up, and, while he's hunched over, crying from the impact, slam the door as hard as I can in his face. How's that?
Old man: 你 don' wanna fight me, I was a WWI veteran. Me: I don't care, I don't have pants. B) Old man: *Gets into an incredibly rusty fighting stance.* Me: *Knees his face with my bare and hairy knee and breaks his jaw.* B) Like a boss!
(Okay, I am rather inflixible, i wouldn't hit his face, but still. XD)
