Suggestions/plots for fun in the wee hours (add +1 if you're interested):
My favorite youtube video - participants will show one video each - a night of video discovery . lot of fun is guarantied + dicussion : the power of sharing - why people are so pasionate to show video to their friends (yossi )
Werewolf [+ 1 from Avi Bryant, but I'd also love to try The Resistance, which sounds like an improvement over Werewolf in a few ways: http://en.wikipedia.org/wiki/The_Resistance_(party_game) ]
Talent Show (With possibly minimal talent required... think stupid human tricks, and a few smart ones) [+1 from Rachel Sklar, inveterate summer camper and talent show-er. Available to provide passable vocal backup and camp-counselor like encouragement.]
Prometheus Field Trip? We could all traipse out to see the much-anticipated sci-fi flick.
