Loretta Swit‘s Major Margaret “Hot Lips” Houlihan had several romances during the 11 seasons of M*A*S*H, but one of her final love interests was played by Dennis Holahan, the actor who later became Swit’s real-life husband.
Holahan appeared in the Season 11 episode “U.N., the Night and the Music,” which originally aired on Jan. 3, 1983. In the episode, three United Nations representatives visit the 4077th to observe the medical unit for 24 hours. Holahan played Per Johannsen, the U.N. delegate from Sweden. Margaret is immediately attracted to the handsome visitor and makes her interest in him very clear. Per likes Margaret, too, but he repeatedly tries to keep his distance from her.
