Season 2

When Lucy wins tickets to see Blink 182 in a competition, Josh is desperate to take them off her hands – after all, he's a huge fan of the band, and Lucy's such a geek she's never even heard of Blink 182. Lucy agrees to give the tickets to Josh, but on one condition: Josh has to perform a truly unselfish deed in order to qualify for the tickets. Of course it's a terrible struggle for the scam-meister, but Josh learns a whole lot about himself in the process. Elsewhere Mel is upset (though refuses to show it) when Trent appears to be going on a date with another girl. The confusion is resolved later in the episode when it turns out that Kelly is Trent's cousin, not his date and he and Mel become friends again.

Josh injures himself during sports, so Brian attempts to fix him with a home-made machine. However, the machine instead makes Josh a chess champion and a maths prodigy by mistake, making Lucy feel threatened as she is outplayed in chess.

Josh wants to have a wild party for his class (including resident tough-guy, Big Verne) so he tries to make the rest of the family go on a holiday. Mel is aggravated by her family's constant need for attention when all she wants some privacy to write a song to enter into a competition with Trent.

Lucy and Wendy are on the verge of falling out, as Wendy is upset that Lucy never invites her to her house. They arrange a sleepover, and Sophie and Brian must act as normal as possible. Meanwhile, Josh is charging Sophie for doing chores around the house so that he can later buy a snooker table.

Lucy is selected to represent the school in a Science Tournament where she has to build a rocket with maximum propulsion – which proves to be too difficult a task for her, so Sophie offers to help. Brian enters one of Mel's photograph's in an art contest. Josh tries to bribe Scott Taylor into letting him join the football team and get to go to Holland and almost loses Frankie and Pete as friends.

Mel goes to school in trousers, as she feels the school rule that girls must wear skirts is sexist, whilst Lucy is looking after the school hamster which Josh promptly loses by trying to make some money with it.

Lucy manages to get her way in the house, organising chess nights and debates. Due to this, Josh gets the idea to run for school council. He claims if appointed, he would get all students entry to the prefect's room, much to the anger of Mel. Mel has a secret weapon – if he continues in his plan, she will blackmail him with a karaoke tape of him singing along to Britney Spears. But then when she puts it on in the school Josh starts to sing and everyone gets dancing so Mel gets annoyed and leaves with a sulk.

Lucy's birthday is arriving, and she wants a party. While she thinks no-one is interested, the family is planning a secret party. When Sophie becomes pregnant, Josh is elected to give Brian 'The Talk' on the facts of life, with help from a book from the school library. However, Brian later becomes pregnant as well. Lucy plans a party with Wendy, will her friends come over, before Brian and Sophie's babies are born? And how will Lucy's party go?

Mel asks Scott Taylor to the school Christmas disco, causing Trent to get jealous. Lucy is cast as Mary in the Nativity play, a part Wendy wants. Josh fills Brian and Sophie in about Christmas. Lucy gives Wendy the part of Mary in the play, but Wendy becomes extremely demanding. Mel gets cold feet and won't go to the disco, so Brian morphs into her and goes in her place. Mel finds out and rushes to the disco, only to find Brian-Mel kissing Scott, right in front of a heart-broken Trent! Mel attempts to repair the damage caused by Brian, only to find out some things about herself. The school Nativity play becomes a strain on Lucy and Wendy's friendship. Josh has nightmares and is visited by ghosts in a plotline similar to that of Dickens A Christmas Carol.
