What Would You Do if a Crazy Person Punched You?

As I'm presently home-bound, afflicted with (according to the doctor) 'probably H1N1,' I have a lot of time to catch up on my intellectual reading...TMZ, Perez Hilton. Fark, etc. One story that caught my attention was the crazy guy that punched Leona Lewis in the head during one of her book signings. Seeing as how being randomly accosted by strangers appears to be part of my going-out-routine, I can't help but a) thank my lucky stars that no one's actually punched me yet, and b) wonder what I would do in such a situation. Well, given how on this past Saturday night at Fourth Street, I had some drunken idiot-girl dressed as a ghoul run up and scream into my face and I responded (much to her surprise and dismay) by getting back into her face and screaming her down and away from me until she ran off, I think I probably would have punched the guy back. Thoughts?

PS - I blame ghoul-girl for infecting me with 'probably H1N1'
