A man is nervously waiting in the lobby of a hospital for his wife to deliver. All the children they've had before have been terribly deformed.
Finally, the doctor approaches the man and says, "Sir please follow me." They walk down a long, dark corridor, and into the wife's delivery room.
She's lying there, crying, with a little bundle in her arms. The man peers over, and moves the blanket. In her arms is a 10 pound eyeball. The man gets down on his knees, and cries, "Oh, dear God!! What could be worse?" The doctor solomnly shakes his head, and says, "He's blind."
