Although the character of Nan would get her own spin-off series, this Christmas special from 2007 was the final hurrah of The Catherine Tate show, and what a way to go out. As ever, there are sublime sketches featuring the extraordinary gallery of characters created by comic chameleon Tate and we also get hilarious guest appearances from Kathy Burke, Tamzin Outhwaite and the late, great George Michael. Plus - shock, horror - teenager Lauren "Am I bovvered?" Cooper goes on a kayaking trip with fatal consequences.
