The city boy replies, "But I shot the duck, therefore it belongs to me!"
The farmer says, "It fell on my property so it belongs to me!" They continue to argue, each claiming ownership of the duck. After awhile the farmer says, "We should settle this the old-fashioned way."
The city boy asks, "What is the 'old-fashioned way'?"
The farmer explains, "First, I kick you in the groin. Then, you kick me in the groin and we continue in this fashion until one of us gives up. The one who wins gets the duck."
The city boy, willing to do anything to get his duck and leave, agrees to the contest. The farmer draws back his leg and kicks the city boy in the groin with all his might. The city boy, in horrible pain, falls to the ground moaning and groaning. After about 10 minutes of this, the city boy stands up shakily and croaks, "Its my turn now."
The farmer says, "Oh, you can have the duck," and leaves.
