In a surprise visit (video below), Conan O'Brien stopped by his old studio during a taping of 'Late Night' and took a moment to shoot the breeze with new host Jimmy Fallon. Conan admitted he was there because he'd forgotten to take something with him when he left NBC for TBS.
"You were here for 16 years," Fallon marveled at one point. "And then what happened?" O'Brien went straight to the couch and retrieved, from behind the pillow, Triumph the Insult Comic Dog. "I can't believe you didn't notice that," he said.
