A duck hunter is out trying to kill a duck, so he can take it home and feed his family. After several hours, with no luck, the hunter gets back in his jeep and heads home. On the way, he spots a flock of ducks flying over a farmhouse. He gets out of his truck and shoots the biggest one which lands in the farmers yard. The hunter leaps over the fence to pick up his duck. He's twenty feet away from the duck when he hears the farmer yell "hey, that's my duck."
"No, no," says the hunter, "I just shot it."
"No matter," says the farmer, "it landed on my farm."
They argue for a while then the farmer suggests that they settle their dispute the country way. "How's that," asks the hunter. The farmer says that they have to take it in turns to jerk each other off and whoever cums in the shortest time loses.
The hunter begins, ten minutes later, the farmer cums. "OK," says the hunter, "now it's your turn."
"Never mind," says the farmer, "you can keep the duck."
