Some Mothers Do 'Ave 'Em

Frank boards the train for his second honeymoon -the first time he landed in the wrong town. At the hotel, things start go really wrong when he tries to push the single beds together, gradually wrecking the whole room. Looking for replacements, he and Betty raid a neighboring room (funny Kenny's room), causing him to complain to manager Bedford about haunting, presuming it's his late grandpa.

Frank manages to mess up the library card system without actually getting a book out; he then returns to the farm supplies firm with one more chicken than he let escape. Frank finds out that the job he's going for with the farm supplies company comes with a company car. He lies he has a driving license and passes the interview with stand-in recruiter Henry. So they take the car for a picnic to the seaside.

Frank takes a course in motorbike riding for a courier job with dodgy Mr. Hunt, who only took him as too dumb to ask questions, but can't even find the route, and the examiner gets run over by a similarly dressed motor-biker. Even his wife Betty dreads the idea of him behind the wheel and deliveries depending on his performance. At home, Frank tries out a self-made metal detector, dreaming of finding Roman remains. At his first delivery, 'deamon king' manages to block the break, starting his usual wild ride, everywhere unsafe. At the other side of the radio, Mr. Hunt has even more trouble with the police, which calls Frank back, just as much a public danger, somehow arriving, even trough the river. CID arrests him too for spreading porn. As if that weren't enough trouble, he decides to defend his incompetent self in court, trusting on character witnesses, who prove painfully honest. This proves him guilty of nearly everything loathsome, but incompetent to pull of the crime.
