A fireman was working on the engine outside the station when he noticed a little girl nearby in a red wagon. It had tiny ladders on the sides and a garden hose coiled in the middle. The girl was even wearing a fireman’s helmet! 
“Thanks,” said the little girl.
But when he looked closer, he noticed the wagon was tied to the dog’s collar — and to the cat’s testicles. 
The fireman gently said, “Little partner, if you tie that rope around your cat’s collar instead, you might go faster.”
The little girl thought for a moment and replied, “You’re probably right… but then I wouldn’t have a siren!”
