The man, the dog, and the cat all sit down at the bar and the bartender says "What can I get you?" The dog looks squarely at the bartender and says I'll take a vodka, the guy will take a water, and the cat will take a scotch." The bartender looks absolutely shocked at the dog and says "This is AMAZING! You're a dog that can talk..." The guy looks at the bartender, and says "Don't be fooled, the cat is a ventriloquist."
This question is actually based from "Ideals of Human Excellence and Preserving Natural Environments" which was written by Thomas E. Hill.
