A J Jacobs.

I'm currently reading 'The Know It All' from him, where he reads the entire Encyclopaedia Brittanica, and a few months back I read 'The Year of Living Biblically' which I absolutely loved. I know he has a third book that i've got on order from Amazon, but I was wondering whether anybody knew any similar authors to recommend?

I have a couple of Dave Gorman's books and i'm checking out Bill Bryson, but any other people I should be having a gander at?
