Three's Company (1977)

S6E25 Up in the Air

Janet is eager to make a strong impression on a wealthy man she's recently met and enlists Jack to be her date for an exclusive ball on a private island. However, Jack, who has a fear of flying, turns to Larry for tranquilizers, much to Terri’s annoyance. Unfortunately, Jack mistakenly combines the pills with alcohol, leading to a wild transformation into a “party animal.”
