Having been resting on the wilting laurels of the triumphant Wayne's World for four years now, director Spheeris hammers a decisive post-Beverley Hillbillies and Little Rascals nail in her own comedic coffin with this asinine stream of charmless drivel.
Farley is Mike Donnelly, a haystack coiffeured, well-meaning dimwit and brother of thrusting political candidate Al (Tim Matheson). After Mike drives the campaign wagon into a cinema marquee at an election rally, Al decides to assign weasily campaign worker Steve Dodds (Spade) as his minder and packs both of them off to a cabin in the country to keep them out of trouble. There they have a fight with a bat, wreck the cabin and meet nutty Vietnam vet Drake Sabich (the woefully unfunny Busey). There's part of a sentimental subplot about a lonely new kid in town, which is abandoned halfway through the movie, and a saccharine buddy motif as Steve realises that Mike might be a cretin, but he's a good-hearted cretin.
The ensuing morass is astonishing in its lack of even basic competence at any level, with a script that over-signposts gags better left unadvertised, and a cast and crew that gleefully mistime them before heading off on their merry way as if the developing farrago was nothing to do with them.
Farley and Dodds, veterans of Saturday Night Live, are in the running for the least likeable comedy duo of the decade and, in a final wilful explosion of idiocy Spheeris shoves a "fuck" in the script thus garnering a 12 certificate and locking out the uncritical eight year olds, who might have been a better audience for this.
