Performance: the late, infinitely more than great Bill Hicks, 1961–1994. RIP. Honourable mention to Bill Bailey—particularly his musical ability, which is incredible.
Writing: Graham Linehan, without a doubt. He's still got lots more left in him, too—I hope so, anyway. Deserves to be in everyone's favourites list for Father Ted alone. Honourable mention to Chris Morris, both as a writer, director, and performer. Brasseye and The Day Today are at the peak of British TV comedy, and nothing comes close to On The Hour on the radio.
