A single mother tried desperately for many years to conceive a child, no luck.
So she finally is artificially inseminated and becomes pregnant. 9 months later, it's time to give birth. She goes to the hospital and gives birth to a human head, with no body. The doctor says, "Don't worry, just plant it in this pot and set it next to the window where it can get plenty of sunlight."
So the woman does just that. As the years go by, the head grows a neck, then shoulders, then a torso. At this point, the little boy can see out the window, and watch the other kids playing baseball. He so wants to go and play too, but he has no legs. But as time goes by, he grows legs, and eventually feet. The mother takes him to the doctor's office and the doctor clips him loose from the pot.
The mother says, "Well now that you're free, what do you want to do?"
The kid replies, "PLAY BASEBALL!"
So she drives home, lets the kid out of the car, and he runs straight over to the baseball field. At his first at bat, he hits a home run. In the field, he makes diving catches and plays like a star. Still, the game is tied in the very last inning, and he's playing center field. A long fly ball is hit, and the little boy gives chase. He runs into the street, gets run over by a car, and dies.
The moral of this story? Quit while you're a head.
