A dog went to a telegram office, took out a blank form and wrote: "Woof. Woof. Woof. Woof. Woof. Woof. Woof. Woof. Woof." The clerk examined the paper and politely told the dog, "There are only nine words here. You could send another 'Woof' for the same price." The dog replied, "But that would make no sense at all!"
