A fire-fighter was working on the engine outside the station, when he noticed a little girl in a little red wagon with little ladders hung off the sides and a garden hose tightly coiled in the middle. The girl was wearing a fire-fighter's helmet. The wagon was being pulled by her dog and her cat. The fire-fighter walked over for a closer look. " That's sure a nice fire truck," the fire-fighter said with admiration. "Thanks'" the girl replied. The fire -fighter looked a little closer. The girl had tied the wagon to the dog's collar and the cat's testicles. " little partner," the fire -fighter said," 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 replied thoughtfully, " You're probably right, but then I wouldn't have a siren."
