A Bit of a Do is a British comedy-drama series based on the books by David Nobbs. The show starred David Jason and Gwen Taylor. It was produced by Yorkshire Television for two series and aired on the ITV network from 13 January to 1 December 1989.

The show was set in a fictional Yorkshire town. Each episode took place at a different social function and followed the changing lives of two families, the working-class Simcocks (David Jason, Gwen Taylor, David Thewlis and Wayne Foskett) and the middle-class Rodenhursts (Nicola Pagett, Paul Chapman, Sarah-Jane Holm and Nigel Hastings), together with their respective friends, Rodney and Betty Sillitoe (Tim Wylton and Stephanie Cole), and Neville Badger (Michael Jayston). The series begins with the wedding of Ted and Rita Simcock's son Paul to Laurence and Liz Rodenhurst's daughter Jenny; an event at which Ted and Liz begin an affair. The subsequent fallout from this affair forms the basis for most of the first series.
