A boy turns 15 years old...

His dad deems him old enough to go to town on his own. Before he sends the boy off he realizes he doesn't have any money to give him. But he has a duck, so he gives it to his son and says "it's better than nothing. Maybe you can get something for it."

So the boy heads to town with the duck. As soon as he arrives a truck barrels by and hits the duck, breaking its legs. Some prostitutes standing out in front of a whorehouse see this. One feels so bad she approaches the boy and says "boy, i feel bad for you. Give me your duck and I will turn you into man."

The boy happily says okay and he goes in. She turns him into a man and 30 minutes later he goes back outside. The prostitute enjoyed it so much she stops the boy as he is about to walk away and says "boy, I enjoyed that so much. I tell you what, I'll give you your duck back if you give it to me again."

The boy happily agrees again and he heads back in. 2 hours later he comes back out, exhausted but satisfied. He has his duck back too. He is tired so he heads back for home. On the edge of town another truck barrels by and hits the duck, this time breaking it's wings.

The driver stops and feels terrible, so he says "boy, I feel awful. I'll give you 15 bucks for your duck." The boy agrees, takes the money and heads home.

When the boy walks in the door his dad asks "how did your night in town go?" The boy says "well, I got a fuck for a duck, a duck for a fuck, and 15 bucks for a fucked up duck."
