Although unlikely to literally split your sides, as the title suggests, this should nevertheless cause one's lips to curl on more than one occasion. In a genre all of its own - teenybopper murder-mystery musical comedy just about nails it - it's utter rot, but has just enough preposterous charm to give it that all-important 'cult' edge. All cabby-cum-musician Robby Benson wants to do is make it to the final of a record contract contest, but when he inherits a monkey which is carrying a top secret computer formula our hero becomes embroiled in plot hatched by an evil boy genius, played by the wonderful Bud Cort (Harold And Maude). It was intended to be a showcase for Benson's copious talents (he co-produced, co-scripted and wrote three of the songs) but it was a vehicle that was to take its child star up a dead-end. But with a storyline that takes in a spider monkey and a Soviet circus troupe, it's hardly surprising.
