A man was walking down the street when he saw a little boy, 4 or 5 years old sitting on a toy red firetruck.

In front of the toy firetruck was a Dalmation dog. The little boy had tied a rope from the firetruck to the dog's testicles, and the poor dog was slowly pulling the little boy sitting on the toy firetruck down the sidewalk.

The man, wincing, decided to give the little boy some advice.

"Hey, sonny," said the man, "I bet that if you tied the rope from your firetruck to the dog's NECK you'd go a lot faster!"

The little boy replied,"Yeah, I would."

The man said, "Then why don't you? I'll help."

The little boy then said, "Because if we tied the rope to the dog's neck, I wouldn't have a siren for my firetruck!"
