There's a mouse in the kitchen, Mum's hiding in the shed, Dad's in charge of the cooking, and Jim is delighted when he ends up invited to have dinner with the family.

It's Christmas Day. Mum has made a fantastic Christmas dinner. The boys are delighted that Grandma is coming round, but horrified that Dad's mother - 'Horrible Grandma' - is coming too.

Adam finally brings a girl home for dinner, but the evening is ruined when the family suddenly have to look after eight-year-old Katie, who has a massive girlie crush on Adam.
