A fireman is polishing his fire engine outside the fire station when he notices a little girl next door in a little red cart with little ladders hung on the side and garden hose tightly coiled in the middle. The little girl is wearing a fireman’s helmet and has the cart
tied to a dog and a cat.
The firefighter walks over to take a closer look, ‘that’s a lovely fire engine,’ he says admiringly.
‘Thanks,’ says the little girl.
The fireman looks closer and notices the little girl has tied one of the cart’s strings to the dog’s collar and one to the cat’s testicles.
‘Little colleague,’ says the firefighter, ‘I don’t want to tell you how to run your fire engine, but if you were to tie that rope around the cat’s collar, I think you could probably go a lot faster.’
The little girl pauses for a moment, looks at the wagon, at the dog and at the cat, then shyly looks into the fireman’s eyes and
says “You’re probably right, but then I wouldn’t have a siren, Would I?”
