Film it?
I once had some mates around for drinks when I was a student. One brought a video camera, and proceeded to spend the next 3 hours filming ourselves getting progressively more pissed.

Probably one of the funniest things I've ever watched. Especially the bit where Rob simulated masturbating with the rather phallically shaped (and pink) Vim bottle, and managed to spluff caustic powder all over the carpet thanks to a vigorous wrist/squeeze technique.
