I Want to Work for Diddy
Diddy's season 2 hopefuls — a pageant queen, a (female) pro football player, eager PR types — battle for Bad Boy ascendancy in a frantically paced hour that comes off as a cross between The Apprentice, Survivor, and some urban hazing ritual/scavenger hunt. B —Leah Greenblatt

Season Finale
Bored to Death
It has now been firmly established that the more Ted Danson is featured in the hipster detective sitcom, the more everyone likes it. And this week's episode is extremely Ted-centric as his magazine chief, Jason Schwartzman's gumshoe writer, and Zach Galifianakis' slacker cartoonist prepare to box an Oliver Platt-led team from GQ. Danson's character proves himself as both a fighter and a lover, but the show is almost stolen by guest John Hodgman, who offers a unique line in taunts while fighting Schwartzman (''Your first novel was amateurish, at best!''). B+ —Clark Collis

10-11PM CBS, TV-14-DLV
