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."
