Discussions of character with the Late Show host.

An out-of-character conversation.

A suburban dad. A fictional television blowhard. And now a political money launderer. How one funny guy became three.

Smigel: Louis comes up with, "What if he says, 'I'm the nurturing president,'and I've developed the ability to breastfeed!" And I'm like, "Yeah, that's great! And then let's have him open the shirt and he's got eight nipples and he can breastfeed dogs and cats." Colbert: We had already lost a lot of sponsors. [Starts singing] It's a beautiful root beer day, the folks from Mug Root Beer have agreed to stay. But you better not breastfeed any puppies today, or you sure as hell will be on your way. So be careful you little punk, Dana Carvey! Even I think it's odd I remember all of the lyrics. I am very impressive...remembering reasons why shows I'm on failed.
