Playing Fireman

[CBI_2]

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!"
