Have you ever wondered why cats purr or whether it can really rain frogs? Bill McLain answers and expands upon these problems, leaving you knowing much more than just a simple answer to the puzzling and improbable questions that he was asked when webmaster for a major website.

As the official Webmaster for Xerox, Bill McLain was responsible for handling all mail from Xerox's external web site. However, he was quickly surprised by the kinds of questions he was receiving, questions like whether people born blind can see in their dreams, where the lowest point on Earth is, and why rabbits are associated with Easter.

McLain began to answer each and every question he received. The result - collected in Do Fish Drink Water? - is a surprising, funny, and informative collection of facts. McLain's answers - often as wild as the questions - prompt entertaining anecdotes about where he found them, and how he's played a role in inventions, long-delayed reunions, and even a marriage or two. He also provides an extensive list of web sites where he conducts research, offering an informative guide to making the most of the Internet.
