It’s an odd choice, but CBS has made it official: Stephen Colbert will replace David Letterman as host of The Late Show once Letterman retires.

I say it’s an odd choice because Colbert plays a character on his Comedy Central show. He’s parodying Bill O’Reilly. Does he bring that schtick to a full talk show at CBS, or does he leave it behind and re-invent himself?

The safe bet would be to stick with what brought him success so far, but the safe bet would not have been to bring Colbert to The Late Show in the first place. Craig Ferguson would have made a good replacement, as he already has a talk show on CBS. He just would have had to move forward an hour, and probably polish up a thing or two. His show carries forward with the wackiness that Letterman had, a long time ago.

Colbert…I don’t know.
