"It was a whole city, run by dogs, and a dog was the mayor, and another dog was a firefighter! That one was a dallmation of coarse! He had spots. So many spots. People say he has the best spots, no, they really do. You can ask anyone. There was a dog waiter, and a dog resteraunt, and they were eating cats and dogs. It's true. It was very sad. I SAW IT ON TV, OK????!!!!"
