The Yellow Pages is a telephone directory of businesses, printed on yellow paper to distinguish it from the non-commercial listings printed on white paper. The concept began in 1883 in Wyoming when yellow paper was substituted for white when a printer ran out. The first official directory was published in 1886, and it is now used globally.

- A telephone is the patient in Dr. Bob's operating room during the "Veterinarian's Hospital" sketch of episode 210 of The Muppet Show. In typical Vaudevillian fashion, jokes fly, including an exchange between Nurse Piggy, Nurse Janice and Dr. Bob.
Dr. Bob, "No but I can look it up in the book."
Nurse Piggy, "The medical book?"
Dr. Bob, "No, the telephone book."
Nurse Janice, "What do you think Dr. Bob?"
Dr. Bob, "It must be jaundice."
Nurse Piggy, "How do you know?"
