You know when Conan O'Brien is a talk show guest that the resulting interview is going to contain plenty of chaos, and his appearance on The Late Show does not disappoint.

In the 23-minute video above the former late night host speaks to Stephen Colbert about his role in A24 drama If I Had Legs I'd Kick You (he introduces the clip in trademark Conan fashion), tells a hilarious story about the time his mom gave advice to Jim Carrey, and takes a more serious minute to say something sweet to Colbert about his future after The Late Show ends next April.

"I, of course, adore you, I love you, I know you as a person and also as a comedic force, and like a lot of people I'm very sad that this chapter is ending," says O'Brien. "But I also want to say that you are going to do amazing things, you're going to have a lot of fun, and the connection you have — and this isn't just you, it's Mr Kimmel, and Fallon, all these guys have — it's very special. The connection you have with your audience, you're taking with you. No-one else owns that. That's yours."
