Check this out. Lamont was planning to marry (I guess he proposed to her) Betty Jean as a way of getting back at Fred. Come to find out that it was nothing but a setup. However, was Betty Jean in on the joke? She thought that she was getting married legit, as did her parents. I thought at first the two of them might've planned it. My question is why would Lamont propose when he knew that he was going to dump her in some kind of way? Everytime I watch that show, I think of it.

That's a good observation. After Lamont proclaims "Betty Jean & I are getting married", the mother runs upstairs, apparently to congratulate her. And later Betty Jean was visibly disturbed when Fred started talking about 7-gallon-a-day water diets and Lamont being a "weight watcher's weight-watcher", suggesting she was *not* in on the scam.

The only evidence that I could see suggesting Betty Jean *was* in fact in on it was the way she reacted when she mentioned the dowry to Lamont. He says something like "you have to be careful Betty Jean, there's a lot of evil old men who would like to get their hands on that money." And Betty Jean says "oh, don't I know it" with kind of a smirk on her face, insinuating that she knew Lamont was talking about Fred.
