What to do with a drunk friend?!

[Somebody Else]

Get a video camera, and film him. Oh, and experiment with a permanent marker. And feathers.

Make him completely regret getting that drunk - and maybe he won't do it again. Plus you'll be able to embarress him quite comprehensively in the future. Oh, and scrawl some random 'phone number on his arm in lipstick, to confuse him further when he regains conciousness.

*edit* Damn! The Frenchman beat me to it... should read more before I post...

Then stick him in the 3/4 prone position in the bathroom or something remove anything from the floor that you don't want covered in sick. He won't die from it (probably). He'll feel dreadful in the morning though. If you're really really worried, to the point of motherly paranoia, take him to the hospital to have his stomach pumped. Or do it yourself.
