"The Boys in the Back Room" is a song written by Frank Loesser, set to music by Frederick Hollaender and performed by Marlene Dietrich in the film Destry Rides Again (1939).
Her winking performance was a parody of her vampish roles in earlier films such as The Blue Angel (1930) and Blonde Venus (1932).
She also sang a German version called "Gib doch den Männern am Stammtisch ihr Gift".
It was featured in the Audie Murphy Western Gunsmoke (1953), sung in the town saloon by Cora Dufrayne, played by Mary Castle.
Also sung by Monique Duchamps (played by Angela Richards) in 1979 in the series Secret Army, episode "Ring of Rosies".
