A gentleman stops by a biker bar and notices a large jar full of twenty dollar bills sitting on a high shelf. He asks the bartender about it, and the bartender tells him that anyone who likes can put a twenty in the jar and then attempt to win the pot by completing three tasks: defeating the toughest biker in the bar in a fistfight, performing some amateur dentistry on the bartender's vicious dog which has a sore tooth, and sexually satisfying the bartender's hideously ugly nymphomaniac wife. The man drops a twenty in the jar, walks over to the biker and knocks him out with one punch. He strides confidently the back room, where the bartender hears his dog give out the most pitiful howl he's ever heard. The man returns and asks the bartender, "Okay, now where's that ugly lady with the sore tooth?"
