The following characters appear in the comedy sketch series The Catherine Tate Show on BBC Two. Comedian Catherine Tate portrays all of the characters featured most prominently in the show, which she created with Derren Litten and her team of writers. Other actors who have supporting roles throughout the series include Mathew Horne and Niky Wardley. Main characters Joanie 'Nan' Taylor 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. When she appears on The Paul O'Grady Show, she is recognised as Joanie Taylor for the very first time as she is referred to as "Nan" by Jamie and as Mrs. Taylor by others. However, when she appears on Deal or No Deal, she is recognised as "Nan". Jamie is a university student, but according to Nan, is unemployed. Nan repeatedly asserts that he is gay, although Jamie has said on many occasions that he has a girlfriend. Lauren Cooper Lauren Cooper is a comprehensive school student with a bad attitude who is most widely known for her phrase "Am I bovvered?". Lauren, her best friend Liese Jackson and her love interest Ryan Perkins are known as yobs. Sketches throughout series one see Lauren arguing with authority figures such as train conductors and teachers, as well as Liese and Ryan. Her behaviour in later series becomes increasingly worse and engages in confrontation more frequently. Lauren Cooper's catchphrase "Am I bovvered?" had made her one of the most recognisable characters of the show. Lauren also appeared in many charity sketches with many famous celebrities, including McFly, David Tennant and Tony Blair. During the 2007 Christmas special on 25 December 2007, Lauren is killed during a kayaking trip, after falling down a waterfall. Her gravestone is inscribed with the message "I Still Ain't Bovvered".
