Mum and Dad get a hot tub, much to the horror of Adam and Jonny, and Jim brings a date round for a disastrous dinner.

Mum's friend Val moves in and causes havoc when she finds that Dad is hiding a tin of 20-year-old meat in his shed.

Dad annoys everyone with his old ventriloquist dummy Lord Luck, while Jonny's recently dumped friend Ben comes for dinner in need of cheering up.

Adam isn't happy when he is forced to play his violin for Mum and her best friend Val, while Jonny is relishing every moment. Dad is obsessed with his old microscope.

The boys are threatened with no crumble if they don’t help assemble a wooden shelf, while Jim’s dog Wilson keeps doing his dollops in mum and dad’s flowerbed.
