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.

Dad is keeping a dead fox in the freezer in the garage because he wants to get it stuffed. But when Mum needs to use the freezer, Dad enlists Adam and Jonny in a desperate attempt to hide the animal.
