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.
