We've all had "one of those days." Yet, even under the most stressful conditions, humor seems to find its way through - at times it's even sharper than your surgical instruments! Dr. Waters was asked by hundreds of readers of his first book, A Heart Surgeon's Little Instruction Book, to create a similar work for all surgical specialties. He responded to the request by assembling a stunning collection of the best one-liners from hundreds of colleagues around the world. Here's a sampling of this book's humor and advice: Recognize when a referral is just someone wanting his or her problem to become your problem. Never let a published article stand in the way of common sense. Your percentages of body fat and moral fiber should never approximate each other. Be wary of colleagues who are more conversant with their billings than they are with their clinical results. Start each case with a clear conscience and an empty bladder.
