Eve decides to enter her band, Bloodmonkey, into Britain's Got Talent. They're not very good. But thanks to a misunderstanding, Simon Cowell thinks her parents are dead, and the sympathy vote looks like it might propel her all the way to the final (where she'll be up against an asthmatic girl in a wheelchair who plays the violin). Meanwhile, Edgar and Wendy go away for their anniversary, but unknown to them their eldest son Dusty has stowed away as a surprise. And Ken attempts to rekindle an old romance with Her Majesty the Queen – invoking jealousy of Squidge.

Edgar shows his true colors by running away and leaving his family for dead during a break-in at the house. Their neighbor Johannes, who has designs on Wendy, saves the day. Shamed, Edgar resolves to man up and goes to his local gym, but decides taking steroids will be quicker and easier. Meanwhile Jason goes traveling in Thailand to find himself and meets someone who looks exactly like him. And Eve accidentally summons the spirits of two great women to guide her with a Ouija board.

Dusty surprises the family by bringing home a girl. An inflatable one. Wendy decides he needs a girlfriend so she hires him an escort – without exactly realising what that word really means. Meanwhile, Eve overdoses on chocolate during a tour of Ken's confectionery factory. Ken has a crisis of conscience about manufacturing food that makes people fat and contemplates selling up to his arch-nemesis and occasional squash partner Richard Branson. And tiny aliens plan to take over the Earth.

Edgar decides it's time for his eldest son Dusty to finally make something of himself, but he's horrified when Dusty lands a job as a banker. Dusty does a brilliant job and is applauded for taking thoughtless risks with large amounts of money including his most daring scheme – gambling the entire country's economy by flipping a coin. Meanwhile Jamie Oliver comes back from the future and his latest crusade is helping kids pass their exams one by one. And Ken attends a psychiatrist to rid of Squidge.

After getting slightly annoyed at work, Edgar is committed to a mental home by Ken. To Edgar's surprise, the place is full of men who are hiding out from their demanding families, and he decides he quite likes it there. Until he realises the place isn't quite what it seems... Meanwhile, Dusty is bitten by a squirrel and decides this has given him superpowers. He starts fighting crime dressed as 'Squirrelman'. And at home, Jason tries to fill Edgar's shoes as the man of the house.

Eve is worried that she'll become boring and suburban-like her parents, so when she meets a gypsy boy it's the perfect opportunity to rebel – and the two of them decide to get married. Her parents don't object as much as they might, though. Wendy's found an old bucket list, and they're working their way through it to prove they're still young at heart. And Ken is offered a knighthood – but will Sir Richard Branson allow it?
