A firefighter is working on the engine outside the station when he notices a little girl next door in a little red wagon with little ladders hung off the side and a garden hose tightly coiled in the middle.

The girl is wearing a firefighters helmet and has the wagon tied to a dog and a cat. The firefighter walks over to take a closer look. "That sure is a nice fire truck," the firefighter says with admiration. "Thanks," the little girl says.

The firefighter looks a little closer and notices that the girl has tied the wagon to the dog's collar and to the cat's testicles. "Little partner," the firefighter says, "I don't want to tell you how to run your fire truck, but if you were to tie that rope around the cat's collar, I think you could go faster."

The little girl says, "You're probably right, but then I wouldn't have a siren."
