Jonny's in a pickle: he wants to split up with his 43-year-old girlfriend/boss, but he's too scared. Grandma offers him some advice, and some dancing lessons in the kitchen.

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.
