A man walking on the sidewalk
noticed Little Johnny was a block
ahead wearing a red fireman's hat and
sitting in a red wagon. It appeared
that the wagon was being pulled
slowly by a large black Labrador Retriever. When he got closer to the lad, he
noticed that Little Johnny had a rope
tied around the dog's testicles, which
probably accounted for why the dog
was walking so gingerly. Smiling, he spoke to the little boy,
"That's really a nice fire engine you
have there, son. But I'll bet the dog
would pull you faster if you tied that
rope around his neck." "Yeah," Johnny replied, "but then I
wouldn't have a siren."
