I’m not sure if you’re more of a Daily Show or Colbert fan, as the two are similar, but opposite types of comedy. Stewart is maybe, Cracked, poking fun at things while informing. Colbert is more The Onion, arguing against things by using reductio ad absurdum.
As such, Colbert is almost always “in character.” The character being a sort of amalgam of every Fox News host out there, though I believe he was originally inspired by Bill O’Reilly years ago. We hardly ever get to see him as Stephen himself, which is why this behind the scenes video is kind of cool.
I’ve always wondered if guests know what they’re getting into when they sit down for a Colbert interview. Turns out, at least in the “important” interviews like this one with John Kerry, he lets them in on the gag, and says they can either play along or refute him. This is in contrast to say, The Daily Show’s correspondent segments where clearly the people on camera have no idea they’re being played. No, I refuse to use the word “trolled” here even if it fits.
