If you like baseball, but often find yourself left out of the barroom or water-cooler baseball chats, grab a copy of MacMillan's Baseball Encyclopedia and spend a few months studying it. It's a good book, and you'll learn a lot about the game. In one season's time, you'll probably be able to contribute a thing or two to those discussions. There are enough statistics, records and numbers to make you appear knowledgeable enough to participate.
