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."
