I like em all but I have it narrowed down to 2 fave characters.
Fred because he was so funny. I remember watching the one where he is on a plane with Lamont and Fred is scared to death of flying. When the plane starts to take off, Fred yells outloud "Oh, I'm not gonna make it!" and it of course embarasses Lamont.
Rollo because he would always try to be nice to Fred and Fred would make those sarcastic remarks to him. It really looked like those remarks were really funny to the actor that played Rollo.
