Mum's excited about the new curtains, but the boys and Grandma think they're horrible. Dad drops Mum's beef casserole on the kitchen floor, so Jonny and Adam head to the pub.

Sheila Bloom - also known as 'Bitchface' - almost runs Adam over on his birthday. When Dad reveals that he used to have a thing with Bitchface years ago, the boys can't believe it and Mum's not happy.

The boys are excited, because Grandma (Frances Cuka) is coming for dinner, and she's bringing her new boyfriend. 'He's not her boyfriend,' says mum, he's her 'male companion'.

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.

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 (Martin's) mother - 'Horrible Grandma' - is coming too. Horrible Grandma turns up with her equally horrible dog, Boudacea, which has to wear an oxygen mask. Horrible Grandma hates mum's 'horrible dry turkey', and mum is distraught when Horrible Grandma brings her own turkey with her to eat. Dad and the boys are jealous, as they too secretly hate mum's dry turkey. After dinner, tensions mount, as the two grandmas have an argument that develops into a proper grandma fight. And then Jim turns up, dressed as Father Christmas...

The family are distraught when Grandma gets engaged to Mr Morris, her horrible 85-year-old boyfriend.

Mum and Dad's anniversary is ruined when Dad paints a portrait of Mum that looks like Margaret Thatcher, Jonny gets a tattoo of a skull, and Jim sleep-walks around their house, causing havoc.

It's Grandma's wedding day, and she's getting married to the horrible Mr Morris. The family are distraught, but will Grandma really say 'I do'?

Dad accidentally invites someone who he used to hate round for dinner: an annoying man who talks with his eyes closed. How will Dad get rid of him?

Adam has finally been recognised for his musical talent. But it's overshadowed when Jonny arrives home and announces he's got married.
