It was a completely bogus game too...
Basically, we took a standard deck, and mixed a joker in with the other cards. We were playing with a few guys and a couple of girls. Basically, if one of the guys drew the joker, they had to do what I did. If one of the girls pulled the joker, the two chicks were going to make out for 90 seconds.
A fair risk/reward situation, don't you think?
