Kate and Allison (Jean and Liz Sagal) are identical twin teenagers with totally opposite personalities! One is serious; one is happy-go-lucky. I don’t remember which has what trait, and it doesn’t matter, because they look exactly the same. They’re dancers, see, and dad (Donnelly Rhodes) owns a dance studio that’s also sort of a health club. Hilarious antics ensue, right? Nope.
In the second (and last) season, the setting was moved from Des Moines to New York. Dad was replaced by the cool aunt, and the girls pursue acting and design school. It doesn’t matter which one pursued what occupation, because they look exactly the same.
Patricia Richardson, a terrific actor who held Home Improvement together for eight years, appears in the first season of Double Trouble.
The openings from both seasons are below. If you wanted to describe the mainstream vibe of the ’80s to visitors from outer space, the first one has you covered.

“Quality” was the last thing I was thinking about when I watched this show as an early teenager; all I saw were two cute twins & that was enough for me.
Which is exactly what they were shooting for. I liked the girls on Too Close for Comfort, and that show was probably worse. I also still had a thing for Ginger and Mary Ann. And I still love Gilligan’s Island.
Brought here because I was watching Married With Children and it made me think of this show. Brought here by Google. By the way, the twins are actually Peg Bundy’s real life sisters. Katie Sagal. Jean Sagal, Liz Sagal.
Also, Too Close For Comfort was not a bad show.RIP Ted Knight.
