43. Give me your underwear
At the last bachelorette party, I went to, one of the girls brought one of the card games. The rule is that you draw a card, and it tells you what kind of crap you have to deal with. There are sentences like, "Kiss a redhead!!" or "Dance with a virgin!" and so on. My card says I asked a stranger to give me his shorts.
At the second bar, I achieved my goal. I almost had someone at the first bar willing, but he told me he would only give me shorts if I gave him my underwear and I wasn't wearing any. The second guy did nothing.
