This web-find is of a stripping game played at a Rhode Island gay bar called Mirabar. The contestants played some sort of game (it's hard to see, but it looks like they're rolling dice or something). The loser of each round removes an article of clothing until one of the guys is left with just a teeny tiny towel to cover his bits.
San Francisco's gay nightlife has gotten somewhat tamer lately, it seems. Why can't we do games like that here anymore? In part, perhaps, because our ABC has gotten rather out of control on such issues (why should it matter in a bar with consenting adults and no children?). Perhaps Wet & Wild or one of the other events in SF could take on the challenge?
