Deal or No Deal (U.S. and all international versions)
I figure that game shows count as kind of "proto-Reality shows", and I couldn't find a topic with yon serach engine, so I've created a topic.
The Aussie version was a huge "Who Wants to be a Millionaire" level hit. The U.K. version apparently is red hot right now. It's popped up in about 30 other countries in the past year or two, and yet the whole damn think is about opening suitcases. Discuss! :lol
We could also talk about Howie Mandel and his OCD, or the fact that ton o' spokesmodels on the U.S. version look like an ad for FHM/Maxim/Stuff combined (for example, Bonnie-Jill Laflin).
