"The Hairbrush Song" was originally titled "Oh Where Is My Razor?" Mike Nawrocki, who wrote the song, was looking for his razor to shave while singing the same melody. When he pitched it to Phil Vischer, Phil thought that it was a bad idea, since kids would be looking for their parents' razors and could potentially hurt themselves. So a hairbrush was chosen instead.
Originally, "The Hairbrush Song" was to feature only Larry singing, and the characters speaking. But when it came time for Lisa Vischer to speak Junior Asparagus' line "Why do you need a hairbrush? You don't have any hair!" in the recording booth, she spontaneously sang the line, and the skit was reimagined as a musical.
The second segment, "The Gourds Must be Crazy", is a parody of Star Trek (1966). The title itself is a parody of the unrelated movie Les dieux sont tombés sur la tête (1980).
The only video in the series where Larry the Cucumber is briefly seen with bottom teeth. The moment occurs when Larry has a candy bar stuck to his helmet; he unsuccessfully attempts to eat it off his helmet and he is shown biting with top and bottom teeth.
