Reality TV is bad for you. Hell, it's just plain bad. Watch a documentary or something instead.
I agree for the most part, but the Joe Schmoe Show isn't really a reality tv show. It's actually more like a parody of one. And a well done parody at that. There is the element of Matt himself, which does lend to it a few aspects of "reality tv", but for the most part it's just good old scripted comedy.
The way they revealed it to him was pretty good too. Instead of just coming out and saying it, they kind of messed with his head a little first. Hutch ends up winning, and then the host gets a message on his IFB and is like "Wait, wait, we have to stop - someone here isn't being completely honest." And then after everyone kinda looks around at each other for a moment, Hutch finally says "Okay, I admit it, my name's not really hutch. It's David Hornsby, and I'm really an actor from L.A." And then he accuses Kip of it too, and after Kip argues with him in his gay voice, he finally gives and Matt hears his normal voice for the first time while he admits that he too is an actor. Then all of them slowly admit to it, and Matt is just like, "WTF is going on??" It was a pretty funny way to do it, I must say.
