Bob..............
The local football coach noticed that Bob, his star player, had so many women hanging around that he couldn't possibly handle all of them.
So one day he asked Bob, "Just what the hell is your secret?"
Bob replies, "Well, Coach, whenever I'm about to have sex, I always whip it out and bang it on the top of the dresser like a hammer. That numbs it and I can screw 'em for hours!"
The coach went home early the next day. He went into the bedroom and heard his wife in the shower.
Seeing a window of opportunity, he tore off his clothes and began to bang his erect member on the dresser.
His wife stuck her head out of the shower and yelled, "Is that you Bob?"
