A post went up this morning on Ain’t It Cool News purporting to pass on word from a South Park staffer who calls tonight’s new episode, “Major Boobage,” “one of the greatest things [he’s] ever seen.” South Park being one of the only shows that we actually wish we watched more often (as opposed to “I should watch more documentaries about the migrant-worker experience”), we’re intrigued.

Apparently the episode is an homage to 1981 cult-classic feature-length cartoon Heavy Metal — a series of sci-fi vignettes whose soundtrack features songs by Sammy Hagar, Blue Oyster Cult, Black Sabbath, Journey, and many more beloved/ironically beloved rockers. (It’s also voiced by a crew that includes John Candy, Harold Ramis, and Eugene Levy; the film’s Wikipedia page explains the project’s Canadian origins and also notes its “unusual amount of bloody violence, nudity and sexuality” vis-à-vis other cartoons.) Completely suckered by what may or may not be a clever marketing ploy, we YouTubed Heavy Metal so as to chuckle more knowledgeably tonight. The first five minutes are above.

Tonight, a shadow shall fall over the universe. Evil will grow in its path. And death will come from the skies … to Comedy Central at 10 p.m. —Ben Mathis-Lilley
