Conan O'Brien and Jimmy Fallon (Video)

Wednesday night, after Jimmy Fallon completed his monologue and arrived at his desk, Conan O'Brien made a "surprise" visit.

The audience greeted him with a standing ovation.

O'Brien said he wanted to come by and check out his old studio.

Motioning to the band, he said, "Hey, Max, your hair looks amazing," speaking to The Roots drummer Questlove.

Quest, of course, looks nothing like Max Weinberg.

O'Brien said he came by for a reason, that he had forgotten something important to him. He went over to the couch and got Triumph, the Insult Comic Dog.



Then, he left.
