Radar’s Hidden Hand
Gary Burghoff, who played the endearing Cpl. Walter “Radar” O’Reilly, hid a personal detail on-screen: he was born with Poland syndrome, which affected his left hand. To keep the focus on his acting, Burghoff cleverly concealed his hand using props like clipboards or by keeping it in his pocket.
Radar’s Farewell
Burghoff’s demanding schedule eventually led him to step back from the show. In season seven, Radar bid farewell in a two-part episode titled Good-Bye Radar, marking his departure from the army. Reflecting on his decision, Burghoff once said, “You either want to be rich and famous, or you want to be a daddy. You can’t do both.”

Margaret Houlihan’s Nails and Nickname
Loretta Swit’s portrayal of Major Margaret “Hot Lips” Houlihan had its quirks. For instance, her long nails—over an inch in some episodes—were hardly realistic for a wartime nurse. Swit also wasn’t fond of the “Hot Lips” nickname, feeling it undermined her character’s professionalism. “She wasn’t just a body part; she was a major in the U.S. Army and deserved respect,” Swit said in an interview.
Plastic Surgery Rumors
Some fans speculate that Swit underwent plastic surgery during the show’s run, noting subtle changes in her appearance, such as a cleft chin and possible nose work. While Swit has never addressed these rumors, they remain a topic of curiosity among die-hard viewers.

Hawkeye and Margaret’s Relationship

Their pivotal moment came in the two-part episode Comrades in Arms, where they spent a night stranded together. Although their relationship didn’t blossom into romance, it marked a turning point in their dynamic, showcasing the show’s balance of humor and depth.

The Longest Kiss
Comrades in Arms came full circle in the series finale, featuring one of the longest kisses in television history between Hawkeye and Margaret. Directed by Alda, the scene symbolized the bond between the characters and the actors, who were among the few to appear in both the pilot and the finale.
