Disco Beaver from Outer Space is an early production by National Lampoon, made for HBO in 1979. The film is essentially a shaggy dog story, leading up to a single play-on-words joke based on "beaver" also being a euphemism for female genitals. At the film's climax, the vampire is frightened by the Beaver; in his delirium, he begins seeing double, thus seeing two images of the Beaver. He cries, "Split beaver!" and disintegrates.
