I didn't know for years that this is an episode of a show called Infomercials which you can watch on Max. The first 5 or so episodes are spoofs of actual infomercials, but then it goes off the wall with episodes like this one. Highly recommended!
Whoa, neat! Apparently they sometimes show up just as blank spots on the Adult Swim TV guide, which I remember seeing in the past but had no idea what it meant.
They even have a Wikipedia page: https://en.wikipedia.org/wiki/Infomercials_(TV_specials)
