ADA Jack McCoy
All the other L&O series, except maybe for the ones with Vincent Denofrio's aspie-genius detective, can go eat a bag of dicks though. Most of them were almost as terrible as the various CSI shows. CSI? Ugh.
Captain Malcolm "Mal" Reynolds
Nucky Thompson
Daryl Dixon
Ralph Kramden
Lucy Arnez
gotta agree with martin - Archie Bunker by far
Barney Rubble now that guy was one hell of an actor. He had to put up with that camera hog Fred. Not to mention Barney's gag falls were better than anything the 3 stooges ever did.
The Doctor. 50 years and counting! They must be doing something right.
Peter Falk - "Columbo"
Don Adams - "Maxwell Smart, Agent 86"
