Jason Biggs' Cash at Your Door

I just wonder how they pick on what house they go to...? Do you sign up or is it really just random bc they know the families before going in the house. I think they should venture out of NYC and go into smaller towns like Seneca Falls. Hehe. When do you ever see game shows or any show for that matter where you can win money go to smaller towns where the people may need the money more bc if you ask me if you live in NYC or any city for that matter you must have some money bc I know it's not cheap to live in the city!
