List of Three's Company episodes

Jack's Other Mother is the tenth episode of Season 5 of Three's Company, and the 88th overall episode of the series.


Jack befriends an elderly woman, Gladys Moore, who comes to regard Jack as a surrogate "son." Gladys' doting nature soon proves rather troublesome when she begins to meddle in Jack's love life.

Plot summaryEdit

When Jack helps elderly neighbor Gladys Moore with her groceries, she returns the favor by showering Jack with a torrent of motherly affection. The home-baked cookies are nice, but as Gladys rips the shirt off Jack's back to mend it, he starts getting worried. His problems escalate when Gladys shows up at the sandwich shop and starts lending a hand behind the counter. Next, she intercepts Jack's beautiful blonde date, Katy, and sends her away as unsuitable.

Note: Suzanne Somers makes another cameo appearance in this episode.
