A firefighter is working on the engine outside the station when he notices a little girl next door in a little red wagon with 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 & her cat.
The firefighter walks over to take a closer look. "that sure ia a nice firetruck," the firefighter says with admiration.
"Thanks,"the girl says.
The firefighter takes a closer look & notices the girl has tied her wagon to the dog's collar & 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."
