A dog walks into a telegraph office, and lets the staff there know that he wants to send a message.
“Sure, what do you want it to say?” the staff asks.
“Woof woof woof woof woof woof woof woof woof woof,” the dog replies.
“Got it. You know, for the same price, there’s still enough room for one more woof,” the staff says.
“Why would you suggest that, the message wouldn’t make any sense,” the dog replies, puzzled.
