A fireman 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 fireman's helmet and has the wagon tied to a dog and a cat.
The fireman walks over to take a closer look.
"That sure is a nice fire engine," the fireman says with admiration.
"Thanks," the girl says.
The fireman 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 fireman says: "I don't want to tell you how to run
your fire engine, but if you were to tie that rope around the cat's collar, I think he could pull more."
The little girl replied: "You're probably right, but then I wouldn't have a siren."
