The King of Comedy

This film has examples of the following:

 * As Himself: Tony Randall fills in for Jerry Langford.
 * Big Applesauce: Rupert must venture into the swarming, chaotic hive of Manhattan from his home in the relatively quiet suburbs.
 * Black Comedy: Perhaps a textbook example.
 * The Cameo: The Clash walking around Times Square; Martin Scorsese as the talk show's director.
 * Cloudcuckoolander: Rupert Pupkin is pretty much the poster boy for this trope.
 * Dark Chick: Masha is Rupert's partner in crime and in many ways the mastermind behind their scheme.
 * Fan Disservice: Sandra Bernhard is mostly nude for large parts of the film; of course it could be considered Fan Service, depending what you're into - in truth she has a pleasant figure.
