“The Colbert Report” host Stephen Colbert got comfortable on “The Late Show” set, chatting with David Letterman about taking over the desk next year.

"I'm going to do whatever you have done," Colbert told Letterman, adding, "I'm thrilled."

Dave replied, "I'm thrilled as well. Paul (Shaffer) and I have been doing this a long, long time. They could have just as easily hired another boob like me. They didn't."


Letterman announced April 3 that he would retire from “Late Show” in 2015, and CBS quickly tapped Colbert as his replacement.
