What caused this hilarious eruption? In A Sunburned Country by Bill Bryson. This is absolutely the best book I have ever read about Australia. It's extremely witty while relating incredible first person experiences and the amazing facts and observations about the history and contemporary culture of Australia.
So we spent the next several hours that way, with me nudging Jim to listen every few minutes, and reading whatever I found incredibly interesting or just plain funny out loud to him. And for once he didn't mind. It's that kind of book. This is the kind of book you want to hand down to family members, recommend to friends and keep in your library forever!
