Hmm I actaully done that to people I where I work. One time we had person arrested for Trespassing who forgot there Id and try to sneak into the building.
He drinks martinis and beer in the movies, and some wierd shit that may or may not be alcoholic and may or may not include human blood in TTOD.

but I'll drink with you at the next party for sure
