A fire fighter was working on the engine outside the station, when he noticed a little girl nearby 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 to take a closer look. "That sure is a nice fire truck," the firefighter said with admiration.
"Thanks," the girl replied.
The fire fighter looked a little closer. The fireman noticed the girl had tied the wagon to her dog's collar and to 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."
