A fireman is sitting in front of the station when he sees a little boy coming down the street in a little red wagon. He’s put little ladders on the side and a garden hose is coiled in the front.

The kid is wearing a fireman's helmet and the wagon is tied to a dog and cat who are pulling the wagon.

"That sure is a nice fire truck you got there." "Thanks," the boy says.

The fireman looks more closely and sees the boy has the wagon tied to the dog's collar and the cat's testicles.

As the red wagon stops in front of him, the fireman observes,

The fireman says, "Little pardner, I don't mean to tell you how to run your fire truck, but if you were to hook that rope around the cat's collar, I bet he could pull harder."

The kid answered, "I know, but then I wouldn't have a siren."
