You heard it when you opened this book. The shoulder-shaking, bellowed roar of laughter. That happy sound is embedded on every page. The printers, bookbinders, typesetters, and finally the editors, everyone that assembled the book you're about to purchase couldn't prevent their funny bone from being tickled. So impressed were they they purchased five, ten, fifteen even twenty or more books for birthday and holiday gifts. Investments in others' happiness rewards us in so many, immediately unseen ways.
