A fireman looked out of the fire station window and noticed a little boy playing on the pavement.
He had small ladders hung on the side of his little red wagon and a garden hose coiled up in it.
He was wearing a fireman's hat and had the wagon tied to his dog so that the dog could pull the wagon.
The fireman thought this was really cute, so he went out and told the little boy what a great looking fire engine he had. As he did,
he noticed that the dog was tied to the wagon by his testicles.
The fireman said, "Son, I don't want to tell you how to run your fire company, but I think if you tied that rope around the dog's neck you’d go faster."
“Maybe,” said the little boy, "but then I'd lose my siren!"
