When you dial the number, you’ll be presented with options to: book a dentist appointment, reach an attorney, report a plumbing issue, address construction concerns, or… talk to a private investigator! Press 1-5 in that order to hear different snippets of the song; you’ll have to call back to hear them all. Don’t worry, you’re probably not actually making any appointments.
