I thought most of the people were bogus. They talk and show how they are extreme cheapskates but only to help feed their gluttonous habits. The main example/story that sticks out to me is that guy that goes around asking for peoples left overs. That dude was fat as hell! Why does he need people's left overs??
The Asian lady in NYC and the one dude that rides his bike 70+ miles seemed to be the only legitimate ones, but the lady is so extreme she's completely ostracized herself to the world which is something I'd never want to do.
Still fun to watch either way :)
