The Australian newspaper had an interview with him a few weeks ago that you can read online here. I love the last two paragraphs that illustrate well his kind of wit; writing about Bryson the journalist says:
He is now planning to take the rest of 2010 off "to read" and may even finally apply for British citizenship. Although Bryson is married to a Brit and has four grown-up British children, "I'm still afraid to take the test because I don't want to flunk it", he says. "I had an American friend who recently did it and said it was really tough. Not questions like 'What's Marmite?' or 'Morecambe and blank', but technical things like: 'To the nearest five, how many MPs are there?' A British citizen would fail."
He would much prefer an interview, "somebody saying, you speak English, you're not on welfare, you're not a pedophile, you're OK". What sort of exam questions would he like? "Well," he says, "something like, 'Mr Bryson, how can we make you more comfortable?' "
