A dog goes to a telegram office, takes out a form and writes: “Woof. Woof. Woof. Woof. Woof. Woof. Woof. Woof. Woof.” The clerk examines the paper and tells the dog, “there are only nine words here. You could send another ‘Woof’ for the same price.” “Are you crazy?” says the dog. “if I did that it wouldn’t make sense!”
