I watched a few clips of Sister Wives and thought it was dumb. I don't much care what others do in their own homes, but I really don't think that is a choice that the modern world will leave alone. I never saw anything about the new wife, but it really seemed to me like the women just didn't want to be alone. Otherwise, well, I don't think they would have latched on to that guy and allowed him to get away with the other wives. The wives were all jealous enough of each other before a new wife was mentioned, so I have a strong feeling they are NOT bound for marital bliss in the future. Personally, I cannot figure out why a guy would WANT to have to deal with four wives! Many guys have a hard enough time with just one wife, lol!! Esp as moody as some women can get while pregnant! I know my husband would not even THINK about it because I am enough of a handful, lol. When I was pregnant I was TERRIBLE even though I worked really HARD not to be. And it got worse with each child, so NO WAY would he want to add more of that chaos - no house would be big enough, lol.
As for the strange eating, I haven't seen that one. TLC has some really strange shows.
