I think many of us like Matt - even when we're poking fun at all the things he does. It's not like we give the actors a free pass - we make fun of them too! That's what these boards are for.
Matt is a very average guy - that makes him relatable and empathetic and likeable. Sometimes I shake my head and wonder how he can't know, but honestly - I probably wouldn't know either.
If in that situation, I would have put my hands on a hooker and wrestled in the fat suit and made any number of inane comments too.(not that you will catch my ass on a reality show EVER)
It will suck for him (at least momentarily) when he finds out the truth, but he's gonna be fine. He'a just an average schmo and there is not a thing wrong with that. Even though he has looked ridiculous at times, I have liked him more and more as the series progressed - I'm not looking forward to him finding out - I dread it almost.
I just like the parody aspect of this show, but for that part to work - someone has to be the schmo. The producers are lucky they got someone as affable as Matt to be it.
I dig Matt - I hope he gets his house, his dog and his girl and his very own Dominos franchise too.
P.S. Welcome to the boards - hope you stick around!
