A man walks into a bar, sits down, and orders a beer. As the bartender is bringing his drink, he notices a large unlabeled jar full of money. His curiosity is piqued, and he asks the bartender what it´s for. The bartender explains that there is an ongoing bet that no one will complete a challenge set by the owner. Whoever completes the challenge gets all of the money in the jar and an unlimited bar tab for life. The man asks what the challenge is. The bartender explains that there are three parts, the first is to chug a bottle of tequila without stopping. The second is to pull a tooth from the stray dog that hangs out in the alley outside. And the third is to fuck the resident dirty old hooker. The man ponders it over a few beers, and finally decides to try and complete the challenge. He pays the $20 entry fee, and is handed a bottle of tequila, which he manages to down without too much trouble. He then proceeds outside, and everyone in the bar hears a series of yelps and growls, and about 15 minutes later the man comes back inside, a little beat up, but still standing. The bartender points upstairs, and the man disappears. The bar is silent for a few minutes, and soon they hear the hooker screaming bloody murder. The man comes down stairs, holds up a tooth and says "I got the whore´s tooth!"
