"The Facts of Life": Seasons 1 and 2.
If you're having trouble remembering which episodes were which, season 1 was the season with Molly Ringwald and other actresses who didn't make it past the first 13 episodes, and season 2 was the season that narrowed the cast down to the quatrofecta: BlairJoNatalieTootie. All this and Mrs. Garrett teaching lessons too. Life is good.
Oh, come on, you know you watched it, and you know you're going to at least Netflix this. We are drawn to "The Facts of Life" as if by some force we can't control.
