David Letterman Announces His Retirement

David Letterman announces that he will retire from the Late Show in 2015. The Internet went crazy trying to guess who would replace him, with many arguing that a woman should take up the network late night post, for once.

Could Joan Rivers finally have her revenge on NBC, for real? What about Chelsea Handler who is leaving her E! show next year?

Or maybe Craig Ferguson deserves the promotion. The field is wide open! Who do you think should replace Letterman?
