A little boy, wearing a big red fire hat, was riding a toy fire truck
down the street. The truck was being pulled by a beautiful Labrador
Retriever. Unfortunately, the rope was tied around the dog's privates,
and as a consequence, the truck was going very slowly. A man walking down
the street noticed how slowly the boy was being pulled and gently said to
him, "You know, son, that truck would go a lot faster if the rope was
tied around your dog's neck." The boy nodded in agreement and said, "But
then there wouldn't be a siren."
