Alf has a stomach bug but Else has blocked the toilet with tea leaves so he has to keep going next door. After decrying immigrants for bringing in diseases, Alf learns that he is carrying a contagious bug himself and has to go into hospital. Rita and Mike gleefully burn his copy of notorious moral guardian Mary Whitehouse's 'Clean Up TV' to prevent further contamination.

When Mike is unable to get into the phone box to place Alf's bet on a horse which ultimately wins, Alf decides it's time for the Garnetts to have their own phone. Despite Mike trying to wind him up by pretending to be the operator, Alf is proud of his new possession but becomes agitated when Else allows Min from next door to come over and use the phone, turning down the volume on the show he's trying to watch.
