Steve Martin has always been one of the most intelligent of comedians (you won't find Adam Sandler writing a play about Einstein and Picasso anytime soon), but this intelligence is manifested in gymnastically absurdist flights of fancy, rather than the politically informed riffs typical of performers like Lenny Bruce. Pure Drivel is a collection of pieces, most of them written for the New Yorker, that demonstrate Martin's playful way with words and his unerring ability to create a feeling of serendipitous improvisation even on the printed page.
