M*A*S*H, which is an acronym for Mobile Army Surgical Hospital, ran from 1972 to 1982. Even if you weren't a fan of the show, chances are you know the sad theme song because of the show's ubiquity in pop culture. Audiences tuned in every week to watch the comedy dynamics of Radar O'Reilly, "Hawkeye" Pierce, "Trapper John" McIntire, "Hot Lips" Houlihan, and Corporal Klinger. The finale was seen by 125 million viewers, making it one of the most watched TV shows in history.
The character of Maxwell Klinger was originally not a series regular. He was in one episode and the writers asked Jamie Farr back for a dozen episodes in season 2. Then the character became a series regular and appeared in 219 episodes.
