FX came out with (another) original series called "The Riches". The basic is a family of nomads end up involved in a fatal car accident, where they assume the identity of the dead people and go live in their house. Jen and I watched every episode that played (Monday on FX), and we both enjoyed the show.
It stars Eddie Izzard and Minni Driver as the parents. For anyone who has seen the show, know that FX announced on May 8th, 2007, that it has picked up the second season, scheduled for a release some time mid 2008 (with the majority of a bunch of other premires, I would imagine).
