A Dog's Telegram

On a slow day with few customers, a clerk at a telegram office looks down from her counter and sees a dog waiting in line.
"Oh, aren't you cute?" she says. "What would you like me to put on your telegram?"
"Bow wow wow, Bow wow wow," the dog replies.
The clerk says in a cutesy voice, "But you can add another 'Bow wow wow' for the same price."

The dog responds, "Now wouldn't that sound a little silly?"
