Cheech is Pedro, a rock singer whose band needs a drummer. He picks up Chong, who has drums.They spend most of the last half of the film looking for grass, not knowing they're driving a van made out of it. Lou Adler's direction is pretty poor (he had produced C&C's albums and went on to direct the unreleased Ladies and Gentlemen, the Fabulous Stains), but C&C had their act down pat by '78 and turned out to be a natural movie-comedy team. Lots of juvenile humor about shit, genitals, and dope (sometimes all three at once). It got a fairly positive review from none other than Pauline Kael, who was always up for praising anything the snobs hated.With Stacy Keach, Tom Skerritt, and lots of really bad punk bands.
