After working out in the gym, Bill, a gay man was in the locker room drying off. He was watching this well-built guy rub vaseline on his chest and, after watching for a few minutes Bill decided to ask why. The guy replied, "It makes hair grow."
Bill didn't have much hair on his chest, and thought that maybe his lover would like it if he did, so on his way home he stopped by the drug store and bought a tub of vaseline.
When his lover walked in later that night and found Bill rubbing vaseline on his chest, he asked him what the hell he was doing. So Bill explained his lover what the guy at the gym told him about it making hair grow. His lover replied, "You idiot, if it really made hair grow you would have a ponytail coming out of your a**hole."
