Fry's English Delight: Series 3, Episode 3: Accentuate The Negative
Stephen Fry Audio Book

Contradiction is an addiction - from philosophical dialectic to the verification of scientific and mathematical hypotheses, and from religious controversy to traditional pantomime exchanges with the audience. "Oh, no it isn't", you may think. Oh, yes, it very much is.Stephen Fry examines various aspects of the subject with language expert Professor David Crystal, theologian Melissa Raphael-Levine, philosopher Anthony Grayling, and Oliver Double, who has made a special study of comedy double-acts, and will reveal just how vital contradiction is not only for cross-patter partners but for the whole of comedy.
