The Guinea Pig Diaries: My Life as a Science Experiment
This is the same guy who read through the entire Encyclopedia and who also spent a year living Biblically. I haven't read the Biblical one yet, but this guy should crack you up. The sheer number of "experiments" he'll put himself through for an article is mind boggling. Spending a month outsourcing his day-to-day tasks, trying to live rationally (just why do we use that kind of toothpaste?), living by a code of radical honesty, or just doing everything his wife says, it's an entertaining read.
