The opening scene, with Buster and Babs being force-fed by Elmyra, was originally created for the episode "The Looney Beginning" but was cut for time. Since this episode was running short, that scene was added to fill the time, and different dialog was used.
This is one of three episodes animated by Encore Cartoons. It was originally intended to air much earlier, as evidenced by its production code of 103, but numerous animation re-takes caused its delay. This is even referenced in the gag credit for the episode: "Number of re-takes: Don't ask."
