One day a girl named Cindy was watching football on TV, and the announcer said that one of the athletes was suffering from turf toe. "Turf toe," Cindy laughed. "Is that like a minor case of athlete's foot or something? Maybe that football player should stop being such a big baby."
Shortly thereafter, Cindy got turf toe herself. "I want to die!" cried Cindy. "The pain is too horrible to bear!"
From time to time, Cindy's turf toe injury recurs. Then Cindy is in much pain, and she wishes she hadn't made fun of the football player.
Moral: Laughter is not always the best medicine.
Alternate moral: Don't mock people's pain unless you're willing to walk a mile in their orthotic shoes.
