Two Pints of Lager and a Packet of Crisps

Gaz hasn't called Donna in the week since their date, to soften her up for an undemanding relationship. The girls are weighing themselves, and Louise finds she weighs more than she did at 14 for the first time since then, and goes on a diet and exercise regime. Donna gives up waiting for Gaz, and goes round to his pad, where her mother phones to invite him round for a meal and to meet the family, including Donna's very forward sister Katie. On Gaz's advice, Jonny is trying to treat Janet mean, to keep her keen, but then goes missing, so everyone has to drop what they're doing and go searching for him.

Donna moves her toothbrush into Gaz's flat, and he reacts badly, thinking it's the first step to moving in completely. Meanwhile, Flo is encouraging Donna to move out of the family home. Louise is getting chatted up by Kev, who, from her description, the other two are convinced is gay - it turns out they are right, and Louise decides to make the best of things by becoming a ‘fag hag'. Janet tries various ways to improve her love life with Jonny, but just makes him suspicious, he thinks that she's been sleeping with a bloke named Pedro, who Gaz made up because he was too drunk to think straight.

Gaz wants to feel more attractive to women, and hones his chat-up techniques, only to be discovered by Donna at a club. Janet accepts an invitation from arty fellow-student Cameron, who doesn't fart, to perform at a student poetry evening, and has to be rescued from her embarrassment by Jonny.

The pitter patter of tiny feet may be just around the corner for Janet and Jonny. Janet turns to Donna and Louise for advice. Louise is her usual tactless self in her reaction, ‘Excellent, I have a single mum friend to show off to my friends at University' while Donna heads to the chemist to buy Janet a pregnancy test. But Janet can't muster up a sample so Donna turns to Flo for hints on possible pregnancy symptoms which, according to Flo, include hot flushes and a passion for Guinness. Jonny has not taken the news about possible fatherhood too well, but several beers down the pub and a talking-to from Louise later he decides that parenthood is perfect for him. When Janet finally has the results from her pregnancy test—Is she or isn't she? And just why is Donna taking such an interest in the whole matter—is there something she needs to tell Gaz?
