A dog goes to a newspaper to print an advertisement. He wants to sell one of his bones. The man at the paper asks what the dog wants the ad to say. "Woof woof woof woof. Woof woof. Woof woof woof." the dog replies. "So, nine woofs?", the man asks, "You know, we charge a flat fee for the first 10 words. You could add another woof for no extra cost." The dog says, "But that wouldn't make any sense."
