Trivia: Barf is referred to in this movie as a "mawg"-half man, half dog. However, in the Russian version of the movie, the word "mawg" is translated as "chelobaka"-a portmanteau of the Russian words "chelovek" ("person") and "sobaka" ("dog"), but simultaneously a pun on "Chewbacca," the Star Wars character of whom Barf was a parody.
Continuity mistake: The head of Mega-Maid mysteriously shrinks in size. After Spaceball-1 transforms into Mega-Maid, the head is gigantic enough for a Winnebago to fly through for a considerable length of time. However, later on in the film, after the head has been jettisoned and crashed on a beach, the head is only big enough to hold a few dozen people. This can be determined by the size of the people coming out of her nose.
