Jim Carrey crashed Jeff Daniels' "Conan" interview for an impromptu Dumb & Dumber reunion

Jeff Daniels was he guest on Conan last night to talk about his new Hulu series The Looming Tower and at one point in the interview Conan O'Brien asked Daniels what it was like working with Jim Carrey on the cult comedy Dumb & Dumber. Daniels gave high praise to his co-star Jim Carrey who "just happened" to be in the building and decided to crash the interview. Harry and Lloyd picked up their report almost immediately.
