Diane Morgan's hilarious Charlie Brooker-scripted alter ego gets a series all to herself, as she narrates her own very personal history of Britain. 'Cunk on Britain' follows in the traditions of 'Brass Eye' is skewering television conventions, and of 'Ali G.' in positing the existence of a most unlikely presenter and interviewer (though in this case, one strongly suspects the interviewees are in on the joke). What makes this unique, however, is the degree of Cunk's stupidity, anchored in the silliest of wordplay but all uttered with a stright face. Does it really merit five episodes? Possibly the appeal palls a little by the end, but there are few other comedies that make have made me smile with the same frequency.
