- The title is a play on the song "Whistle While You Work" from Snow White and the Seven Dwarfs, although the song has nothing to do with this episode's story.
- In production order, this episode is the first appearance of Quackerjack, but it ended up airing after "Days of Blunder" and the "Just Us Justice Ducks" 2-parter, two other episodes he appears in.
