The two late night hosts each stuck their heads inside opposite ends of a small cardboard box with a camera inside.

“Thanks for joining me in here, this is nice,” Colbert said, to which O’Brien replied, “I wouldn’t miss this for the world.”

Colbert continued, describing O’Brien as a kind of mentor and asking him what insight he will gain with 11 more years as a late night host.

“You’re gonna learn, never humiliate a guest,” O’Brien told him.
