17. 'Trapper John, M.D.'
So whatever happened to Mash's lovable rogue/Hawkeye's best friend "Trapper" John McIntyre after he bid adieu to his cohorts in the 4077th Mobile Army Surgical Hospital, you ask? He became the chief surgeon at a San Francisco medical facility, that's what. Former Bonanza star Pernell Roberts stepped into the scrubs and gave us a kinder, calmer Trapper, one who tried to teach younger physicians like Gregory Harrison's wild and crazy Dr. George Gates (nickname: Gonzo) how to behave. Not that the older sawbones didn't skirt the rules in the name of good bedside manners, but for seven seasons, this medical drama made a case for bending the system instead of trying to break it. DF
