Phew, what's that smell? It's Suits, a lowly spoof on the advertising industry (have any of these kind of films ever been funny?) featuring a whole host of bad actors, and headlined by Robert Klein as the film's sole "star." I don't have much to say (the plot revolves around developing a maxi-pad campaign) except it's just plain bad -- better than watching commercials, maybe -- but not quite as good as leaving the TV off.
Perhaps the first, and certainly the best, entry into the mockumentary genre. Spinal Tap is responsible for so many American aphorisms (like "turn it up to 11") that it ought to be in the National Film Registry. Insanely funny.
