Three guys in a cell are just starting life sentences... The first guy pulls out a deck of cards and says, ""We're going to be here a long time, so when we get bored we can play poker."" The second guy says, ""Great idea. I brought a harmonica, so when we get sad I can play a song to cheer us up."" The third guy pulls out a box of tampons. ""What the hell are they for?"" ask the first two guys. ""Well, it says on the back that I can ride, swim, ski, *and* play tennis with these.""
