The short uses 'Synchro-Vox', which is a technique that superimposes real-mouths over artwork.
This short film is all homage to the extremely low-budget series by 'Cambria' productions (which included "Clutch Cargo" and "Space Angel").
This short film was included on the 2-disc DVD release of The Incredibles with the F word on the commentary of the short was not heard and it was edited out. However, when the short film was included on the Blu-ray release of The Incredibles, it implies that the F word was used on the commentary of the short, but was bleeped out twice.
