Lil' Firefighter

[Cooperman]

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 sides and a garden hose tightly coiled in the
middle. The girl is wearing a firefighter's helmet. The wagon is
being pulled by her dog and her cat. The firefighter walks over to
take a closer look. "That sure is a nice fire truck", the
firefighter says with admiration.
"Thanks", the girl says.
The firefighter takes a closer look and notices the girl has tied
her wagon to the dog's collar and the cat's testicles. "Little
Partner", the firefighter says, "I don't want to tell you how to run
your rig, but if you were to tie that rope around the cat's collar,
I think you could go faster."
The little girl replies thoughtfully, "You're probably right, but
then I wouldn't have a siren."
