I do not watch this show. Okay, fine, I've seen 5 minutes here or there while channel surfing. Anyway, they had some insane Christian woman on the show recently and she has become the "breakout" star of the show (someone even produced a bobble-head of her, which is apparently for sale on eBay). For your viewing pleasure, I give you The God Warrior:

Sure, she's angrier than William Hung, but can you dance to it?
ETA: Upon rereading of the realityblurred blurb on this, it turns out the show in question was Trading Spouses, not Wife Swap. Color me embarrassed. I'm not sure if I've ever seen any of that show while channel surfing, but the rest of my post stands unedited (except for the needing to edit it part).
