Jim has made a cake to celebrate his dog Wilson's birthday, while the family return from a spin in Jonny's new but uncool company car to find something awful has happened to the house.

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.
