Born the son of poor black sharecroppers, Navin Johnson sets off to seek his fortune in the big wide world. Initially he doesn't get further than the end of the fence, but eventually he finds employment at a gas station, becomes the target for a crazed psycho-killer (the splendid M Emmet Walsh), finds out about his "special purpose" from a female circus daredevil motorbike rider, realises true love with Bernadette Peters, and finds fame and fortune through his brilliant invention, the Optigrab.
Loud and ludicrous, The Jerk is a strong contender for the funniest film of all time.
