I was watching that wedding marathon yesterday on TLC too (it's funny the stuff you'll watch when you're getting married and there's nothing on on a Sunday), but when it got to Made of Honor, I turned the channel after about 30 seconds..
It reminded me of that show "You want to date my Dad?" (in fact, I'm almost positive it's the same producers).. They made the potential 'mom's run through hoops the same way, and wrapped things up with the lovely lie detector test.. I thought it was ridiculous then - but it seems even worse for someone's Maid of Honor - If I was one of the contenders, I would have told her where to shove that title!
