The Know-It-All: One Man's Humble Quest to Become the Smartest Person in the World, by A.J. Jacobs

Again, a very funny book by A.J. Jacobs, this time tracking his quest to read the Encyclopaedia Brittanica over the course of a year. Filled with trivia.

The Year of Living Biblically, by A.J. Jacobs

A. J. Jacobs spent a year trying to live obeying the 720 rules he found when reading about 10 different versions of the bible. From the 10 commandments to the wildly obscure, his quest to find out how relevant ancient moral and ritual law is in the 21st century is definitely entertaining, and surprisingly thought provoking. He is, of course, a trivia fountain, but about halfway through the book, he seems to take what started as a jokey experiment much more seriously, and really tries to find out what his own faith means. Good, fun read.

The Guinea Pig Diaries, by A.J. Jacobs

Very funny book by A.J. Jacobs, his out-sourced assistants, and his long-suffering wife Julie, who has put up with the year he read the Encyclopaedia Brittanica, and, more stressful, the year he attempted to obey every single rule in the bible.
In this one, he tries a smorgasbord of things- he tries to live as George Washington would have, he tries to outsourse his life, he tries to focus on one task at a time, radical honesty, and more with funny and profound insights. Good read.
