Hasu (House - 1977) a seminal cinematic work with strong arthouse appeal that nevertheless cannot be described as good. The Japanese surrealist work features a number of girls with names like Kung-Fu and Gorgeous who visit an ailing aunt and are summarily eaten to feed a dark power. It is inventive and ABSOLUTELY wacky at times, and in my opinion, rife with riffin' material.

It's on Hulu right now for free, part of Criterion Collection. Lots of "class"...
