I'll have to catch that when I get back into town tomorrow...that, along with the last episode of Colbert before he finally puts Letterman out of his misery.
I'm very curious to see how he presents himself on Late Night. Once the character's gone, will he design a new explicitly false persona? It is what he does best and what won him the job, after all. Then again, I remember the few interviews he did as himself, when he was just genuinely curious about what his guests had to say, and they were bloody excellent.
