First off, how about this: Some of these guys were paid to cooperate with the producers, to follow some sort of scripting or otherwise control, alter, or direct the outcome of the show?Whether or not they have actually gone out and auditioned to be in a Shampoo commercial is besides the point.
The point is that some of these guys are not genuine contestants at all. There are clues all over the freaking place.
And while it's true that all contestants are paid to be on these shows, it's not necessary, or normal, to post that disclaimer at the end of the show.
I'll leave it all to speculation until another show or two airs and then I'll come back. But I find the whole thing tranparently manipulated, yet still funny. In fact, the manipulation makes it more palatable.
Watch and see: someone will be humiliated, but the one humiliated will turn out to be on the dole.
