When drinking beer out of a bottle, one might try to peel off the label. People who have tried it, or seen others try, know how hard it is. Supposedly, once you have the label completly off and perfectly inatct, you are able to redeem this label for sex with a person of the opposite sex.
Woah! Chris just got himself a sex coupon, I wonder if Jessica has a double coupon day so I can get some action too.
