One of my favorite characters on "The Red Green Show" is Ed Frid, the nervous animal control officer.
I do find Rowen Atkinson (either as Blackadder or Mr. Bean) pretty funny at times, but a little bit definitely goes a long way!
One bit he did on "Mr. Bean"—sitting on a park bench next to another fellow and making a sandwich while the fellow watched in horrified fascination—was pure Charlie Chaplin. Hilarious!
When he's in comedy mode, Hugh Laurie (especially in the Jeeves and Wooster shows) always reminds me of a chicken who suddenly realizes that he's just accidentally flown through an electric fan.
