The Little Fire Engine That Could
A small boy, wearing a big red fire hat, was riding his little toy fire engine down the street. The truck was being pulled by a beautiful golden retriever. However, 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 the boy was being pulled, leaned down, and gently said, "You know, son, that truck would go a lot faster if the rope was tied around your dog's neck."
The boy nodded in solemn agreement and replied, "Yes sir, but then there wouldn't be a siren!"
