Mama's House

Because Austin and Lindsey had no idea what I was referring to when I mentioned that Lindsey's roommate situation reminded me of a bad sitcom, from Wiki:

The story centers on Janet Wood, Chrissy Snow (later Cindy Snow and Terri Alden), and Jack Tripper living in an apartment complex owned by Mr. and Mrs. Roper (later by Bart Furley and managed by his brother), in Santa Monica, California:, their misunderstandings, social lives, and struggle to keep up with rent.

Jack is studying to be a chef at a technical college and happens across Janet, a florist, and Chrissy, a secretary, in need of a new roommate. Due to Stanley Roper's intolerence for co-ed living situations, even in a multi-bedroom apartment, Janet tells him that Jack is gay. Helen Roper figures out Jack's true sexuality in the second episode, and does not tell her husband, her bond with the three roommates grows until the Roper's departure, and she often sides with them over her husband.
