So, a man is waiting outside while his wife/girlfriend/weirdo thing is giving birth to their child.
A doctor comes running out, "Your child can fly! Come see!"
So the man goes in and the doctor picks up his newborn baby, and lets go of him in mid air. The baby hits the ground with a sickening thud.
The man is disturbed and wants his child, but the doctor says "No! I'm serious!"
The doctor takes the baby to a nearby window, opens the window and throws the baby out by its leg. It smashes into a windshield and explodes in a shower of gore.
The man is about to beat the living stuff out of the doctor, when the doctor says, "Just kidding. It was a stillborn."
