10x70 - Late Show with David Letterman

Mailbag: Dave shows an ad for the mother of all reality shows, ""Bachelorette Millionaire Boat Survivor Race Factor Idol."" He also tries to make sense out of ""Rael"" (Gerard), a Quebecois cult leader who supposedly cloned the first human earlier this week. After revealing the first cloned baby is really a dog, he rebounds with ""Rael's Pigskin Pick of the Week.""
