It wasn't THE prom hair episode, but a similar one.
The "perfect" wife who has never done anything to make MIL hate her, and MIL is a big fat biitch who needs to mind her own business because she's ruining their marriage, and everything is her fault and that woman will never see MY kids again if she doesn't shape up!
The best part was the husband in this one straight up told his wife that most of the problems between her and his mom were his wife's fault. LMAO.
Re: MW
The whole show was supposed to be about the in-law relationship (and how the MIL was ruining everything) and I don't think the woman said 2 words the whole time. The husband and wife were going at it, blaming each other for everything the whole time while the MIL just sat there all smug and smiling. Fantastic.
