1. Blazing Saddles, a period-piece whose racial jokes might make it impossible (or at least inadvisable) to market in the Age of Woke.
2. Young Frankenstein
3. High Anxiety, an extended (and also now dated) parody of Alfred Hitchcock films, with which an audience has to be thoroughly familiar in order to "get it." Brooks's scene as a Sinatra-esque lounge singer is especially memorable.
4. The Producers, for the component ITE cites above.
5. History of the World, Part I, which introduced us to the concept of the stand-up philosopher.
