Egghead is a person who's suffering from an extreme mental disorder which causes him to act out violently, and (HEY DR. Z WHATCHA DOING). I'm working right now, Egghead. Did you really need to surprise me like that? (NO, BUT IF I DIDN'T, I WOULDN'T GET TO SHOW YOU THIS CHAINSAW I MADE THAT COOKS TOAST). Why do you have something like that? (TO KILL THE GINGERBREAD MAN). Go find John I’m working (FINE). He is a very unusual case, not to mention he is the only known surviving case today.
