Wayne's World (1992)

Two amiably aimless friends broadcasting a public-access show from a basement in Aurora, Illinois, with no ambition beyond rock, cars and the next joke. Wayne and Garth started as a Saturday Night Live sketch, and the film keeps that loose, quotable silliness for a full feature. The reason it belongs at a celebration is the "Bohemian Rhapsody" scene: Wayne, Garth and their friends lip-syncing and head-banging in a beat-up car is the purest picture of blowing off steam ever filmed. Fair warning: the room will try to do it too.
