A fireman was working on the engine outside the station when he noticed a little girl nearby in a little red pedal car with little ladders hung off the side and a garden hose tightly coiled on the bonnet.
The girl was wearing a fireman's helmet. The pedal was being pulled along by her dog and her cat.
The fireman walked over to take a closer look.
"That's is a nice fire engine," he said with admiration.
"Thank you," the girl replied.
The fireman looked a little closer and noticed the girl had tied the pedal car to her dog's collar and to the cat's testicles.
"Little girl," the fireman said, "I don't want to tell you how to run your appliance, 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."
