Happy Days (1974)

S08E01 No Tell Motel

Title: No Tell Motel Plot: Howard grows concerned about Joanie's frequent outings with Chachi, so he proposes giving her a personal phone if she promises to avoid Chachi for a fortnight. Unbeknownst to him, Joanie and Chachi plan a secret trip to a concert in Chicago, where they find themselves booked into the last available room—a honeymoon suite at a local motel.
