 David Lynch had begun experimenting with the technique in 1971, and had originally planned to use it in his 1977 debut feature, "Eraserhead", before it finally found use in this episode.Describing the process of learning his lines backwards, Anderson notes that he first worked out the phonemes of each word rather than simply reading it back to front, and disregarded the inflection of any given word as this helped bolster the discordant effect of the end result.The reversed audio was also altered with a slight reverb effect.
