It's interesting how 99% of the people he chooses have huge homes, always clean, how does that happen. Just once, I'd like to see him choose someone who's home is small and messy. It seems like a set-up to me. The "contestants" must be chosen ahead of time for their affluence. They probably have their maids clean up before Curtis is allowed to enter. Maybe they see what people are driving BEFORE he speaks with them in the supermarket. Also, on the way home, they always pass a gourmet store and he knows exactly where it is. This is a little too convenient and certainly shows that this is not just happenstance, but preselecting goes on.
