This clip is from Blazing Saddles. Mel Brooks (and very possibly Richard Pryor, who was a writer on the film) created a brilliant segment that manages to cut right to vicious racist heart of the u.s. in ways that only satire can achieve. I hesitated to add this clip in with eminently serious songs, but the songs speak for themselves, and the use of satire is deadly serious. The best satires crush your heart and make you laugh a the same time. Absurd, non?
