The foul-mouthed grandmother is an old East London woman who constantly swears at and criticises other people. She is always visited by her well-mannered grandson Jamie (played by Mathew Horne), where the visits usually start off well enough, with the Nan showing how grateful she is that her grandson has come to see her. However, things usually take a turn for the worse after she starts to make unfavourable comments about her neighbours, family, and home help visitors. Nan also appeared on "The Paul O'Grady Show" and the Channel 4 game show "Deal or No Deal", hosted by Noel Edmonds. The latter sketch was shot especially for Comic Relief 2007.
