This book presents the best of them: pipe-smoking robots, clairvoyant pennies, zoo jailbreaks, literary cannibals, corned beef in space, revolving squirrels, disappearing Scottish lighthouse keepers, reincarnated pussycats, dueling Churchills, horse spectacles, onrushing molasses, and hundreds more. Plus the obscure words, odd inventions, puzzles and paradoxes that have made the website a quirky favorite with millions of readers -- hundreds of examples of the marvelous, the diverting, and the strange, now in a portable format to occupy your idle hours.
