So there was this farmer, his son, and the only animal on their farm that survived the winter: a duck.
One day the farmer was sitting down paying off last month's heating bill when he realized that they were broke. He told his son to go into town and sell the duck for as much money that he could get.
So the boy started off to town. He came up to a prostitute that was uglier than the ass of the duck he carried in his arms. The hooker looked straight at the boy and said, "The fucking begins at $10, you got $10?"
The boy had no money, so he started to walk away, but the hooker stopped him and said that she would accept that duck in his hands instead of $10. The boy gleefully accepted, so they went off and had sex.
An hour later, as the boy was leaving, the hooker pleaded that he fuck her again because it was the best fucking of her life. She offered him the duck back, and they went at it again.
Another hour passes, and the boy heads home, duck in hand. On the way, the duck gets spooked and flies from the boy's hands. It flew directly into the path of an oncoming car, obliterating the duck. The man driving gets out and appologizes for the boy's duck. The man hands the boy 25 dollars for his trouble and goes on his way.
Later, the boy goes home and hands his father 25 dollars. The father notices that his son looks exhausted and asks him, "What happened?" The boy's reply was this: "I got a fuck for a duck, a duck for a fuck, and 25 bucks for a fucked up duck."
