When the switchman on duty answers the call, Stevie announces that he's from the division of the phone company that publishes and distributes printed materials. "We have your new Test Number Directory," he says. "But for security reasons, we can't deliver your copy until we pick up the old one. And the delivery guy is running late. If you wanna leave your copy just outside your door, he can swing by, pick up yours, drop the new one, and be on his way."
