Transfer!

In a commercial for Discover Card, a woman who doesn't have Discover Card calls up her credit card company, saying it's the third time she's called and wanting to speak with a supervisor. She gets Peggy, who promises that the supervisor is genius and that he'll transfer her to him. But the "transfer" is him passing around an old-fashioned rotary phone with a really long cord until the call comes back to him.
