Alias Jack Tripper is the fifth episode of Season 8 of Three's Company, and the 155th overall episode in the series. Written by Mark Tuttle and directed by Dave Powers, it first aired 1 November 1983 on ABC-TV.


After he finally gets a date with Sharon Gordon, Janet reminds Jack that he promised to spend the day with her childhood friend, Agnes Platt, who's in from out-of-town and dying to meet him. Not wanting to upset Janet or Sharon, Jack talks Larry into taking Agnes out, with Larry posing as Jack. It turns out that Agnes and "Jack" (Larry) hit it off so well that Agnes cancels her flight and invites Janet and Terri to join her and "Jack" (Larry) for drinks. The real Jack tries to keep the girls from finding out about their switch and almost pulls it off until Sharon Gordon arrives, blowing their cover. Jack, who started out with two dates, ends up with none.
