"The Boys in the Back Room" is a song written by Frank Loesser, set to music by Frederick Hollander and performed by Marlene Dietrich in the film, Destry Rides Again (1939). It is often referenced as "See What the Boys in the Back Room Will Have".
Her winking performance was a parody of her vampish roles in earlier films such as The Blue Angel (1930) and Blonde Venus (1932). The song became a standard part of her repertoire, second only to "Lili Marlene".
She also sang a German version called "Gib doch den Männern am Stammtisch ihr Gift".
