Stephen Colbert.
He'll be dropping his conservative caricature persona for the switch
I was wondering if that was the case. To be honest, I only know him as the Colbert Report Colbert. Not as normal Colbert.
it's funny because colbert (with a hard T), the real stephen colbert, is one of the most down to earth and affable people around. the character he plays on his show is arrogant, essentially the complete opposite of what he's like in real life. guy's got charisma though, no doubt about it.
