(CNN) It's been several years since Jim Carrey and Jeff Daniels were on the big screen together, but if Carrey's surprise appearance on "Conan" on Tuesday night proved anything, it's that some classic pairings just go from fun to funner over time.

Daniels had been on "Conan" to promote the season finale of his Hulu series "The Looming Tower" when the subject turned to his iconic character in "Dumb and Dumber." Carrey then entered the stage to a hero's welcome.

"I thought for sure they'd tell them but that's great that they didn't 'cuz I wanted to come out here and say it in front of the world," Carrey said, pausing for comedic effect. "...You're in town, and you don't call me. Not an email, nothing."

Daniels smiled, "I knew it was coming."
