Jon Stewart and Stephen Colbert have enjoyed a highly successful symbiotic relationship for over a decade now, alternating between being friends, colleagues, collaborators, and joint party-throwers. But in all the years that the The Colbert Report (for which Stewart is an executive producer) has been on air, he's never actually appeared on it as a guest—until last night.

Stewart was on the show to plug his new movie Rosewater—but Colbert treated him just as he would any other libtard who considers himself "an arbiter of biblical law." Watch the interview below, which includes a lot of palling around between the two old pals.

Stewart was also on Jimmy Fallon this week, which you can see below.

Reminder: there are only 12 episodes left of The Colbert Report. Cherish them.
