This Is America(1977)

Inspired by shock-documentaries like Mondo Cane, this film looks at the wilder side of life in America. Starting off with the bloodier side of the American car culture by showing a series of crashes at race events, the film then goes on to lesser-known sexual practices. Included among these is a porno movie award show, a nude beauty contest, a sex therapy session, and a detailed explanation of where dildos come from.
