The song is also heard in the 1988 film Splash, Too, the sequel to the 1984 film Splash during a scene when Allen and Madison fix up their new home that Allen's brother Freddie got for them after he sold his apartment and afterwards Madison whistles the song as well while making Breakfast.
A children's parody version of the song often uses lyrics such as "Hitler is a jerk, Mussolini is a weenie." (Or in a more vulgar vein, "...Mussolini bit his weenie, now it doesn't squirt (or "work" in another version)!" or "...Mussolini chopped his weenie, now it doesn't work!" ) Several variants are cited in Iona and Peter Opie's survey, The Lore and Language of Schoolchildren.
The song was also parodied in the British sitcom Dad's Army where Pike remarks "Whistle while you work, Hitler is a twerp. He's half barmy, so's his army" to a captured German officer.
