My favorite of the reality shows (especially since they often visit areas that I've traveled around the world).

] The fourth edition of the show will make its debut with a
] 90-minute episode at 8 p.m. ET Thursday, May 29, settling
] into the timeslot occupied by "Survivor" during the
] regular season. As before, 12 teams of two people will
] race around the world, competing for a $1 million prize.
] The last team to reach each interim destination is
] eliminated.
