Marge thinks Becky, a girl who was going to marry Otto, but broke up after Marge tries to fix their marriage, is trying to kill her. A really bizarre episode. I should probably dislike this episode a lot. I mean, Marge trying to kill Becky was almost unwatchable. It has some laughs, but nothing really funny. The first act is the best of the three. I think it got worse a little more each act.
And the end with Becky admitting she WAS trying to kill Marge was bad, I think. Kinda dark, pretending to be funny.
Overall, an episode I should not like, but I do.
