A fire fighter 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 fire fighter's helmet and has the wagon tied to a dog and cat. The fire fighter walks over to take a closer look. "That sure is a nice fire truck," the fire fighter says with admiration. "Thanks," the girl says.

The fire fighter looks a little closer and notices the girl has tied the wagon to the dog's collar and to the cat's testicles. "Little Partner," the fire fighter 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 replied, "You're probably right, but then I wouldn't have a siren"
