A fireman looked out of the firehouse window and noticed a little
boy playing on the sidewalk. 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. He 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 truck 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 or anything, but I think
if you would tie that rope around the dog’s neck you would go faster.”

“Maybe so,” said the little boy, “but then I’d lose my siren!”
