A man walks into a bar

One Saturday night a man walks into a bar. As soon as he walks in he sees a large jar of coins on a table next to the door. He asks the bartender, "why is that jar of coins there?" To which he replies, "We have a challenge in this bar. You can win the jar of coins if you can skull a liter of tequila in one minute, remove a tooth from the rabid dog at the back of the bar, and have sex with the 90 year old virgin woman upstairs." The man thinks it is a stupid challenge and walks away. A few drinks later he goes up to the bartender and accepts the challenge. He skulls the tequila in 50 seconds. He then makes his way outside to take the tooth of the rabid dog out. As the door closes the patrons hear loud growls and roars. They hear the ripping of clothes and the screams of the man. Then silence. The man walks back inside, a smile on his face and says, "so where's the old lady that needs a tooth removed?"
