My TIVO recorded CASH CAB on the Discovery channel.

While I kind of enjoyed the show, I noticed something at the end that ruined it for me.

The concept is and I quote: Unassuming people enter the "Cash Cab" as simple passengers taking a normal taxi ride, only to be shocked when they discover that they’re instant contestants on Discovery Channel's innovative new game show!

But at the end of the show it said, some contestent are pre-screened by the producers.

Anyone see this show any ideas what they ment by that disclaimer.
