Directed by Danny Leiner, starring Ashton Kutcher and Seann William Scott

Bill and Ted are dead, long laugh Jesse and Chester (Kutcher and Scott). In what ranks as a new level of giddiness for the me-joke you-audience buffoonery of American teen comedies, our two slackaday stoners must negotiate a challenge worthy of Hitchcock: finding Jesse's car because they can't remember where they left it the night before. Along the way they veer wildly (and often very funnily) into plot cul-de-sacs: drug smoking dogs, transsexual strippers, gay Scandinavian aliens and space-obsessed religious cults combining to give the boys the baddest of trips. The script seems to have been concocted through a haze of smoke and leftover pizza at 3am and halfway through you'll give up on the storyline completely, content instead to wait for the next moronic set piece to transport you back to a time in your life when people making noises with their hands under their armpits was the last word in humour.

While Kutcher is cute and effective as the slightly more intelligent glamour boy of the two, it his Scott who steals every gag with his pudding bowl haircut and I-am-five grin. Having built up a profile as the teenager of choice in films like 'American Pie', 'Final Destination' and 'Road Trip', he pawns his last threads of respectability in favour of bargain basement jokes - witness his distress when a policeman beats up a mannequin in an interrogation room ("leave him alone, he doesn't know anything!") and his trouser-tussling joy when he breakdances with some go-go girls onstage at a club. If Jesse and Chester were on TV they'd make their 30 minutes the best medicine in the world, here they outstay their welcome for 85 but guarantee a legacy in video shops worldwide. See it with some friends and dribble together or go solo and feel absolutely no shame at laughing yourself silly. But don't bring a date - they'll dump you straight afterwards.
