On the surface, the joke is not bad at all... but the novelty wears out quickly, when you take a joke fit for a quick gag and stretch it out to an 11 minute sketch.
Basically, the character of Dip Dunham is an extremely innocent man who only see a revolutionary kitchen device when the rest of the world sees... um... something else. It does a good job of parodying the repressed and censored infomercials from the 1960s; it just added to Dip's blissful ignorance, whereas when we switch to modern times it becomes too obviously which direction this is gonna go (especially when hiring porn stars... what, I only know this through IMDb, lol).
In general, a solid joke in itself that just should have ended sooner.
