This book does not claim to be a scientific dissection of the geologist and his fascinating yet challenging profession. Rather, it attempts to reveal some of his characteristic traits and shortcomings with the help of humor. Like scientists from a number of other fields of knowledge (physicists, chemists, biologists, doctors, mathematicians, etc.), geologists also have a highly developed sense of humor, which allows them to get out of various critical situations or make their difficult work more enjoyable. Everything in the book is just "a joke," although in places many of the situations and results seem almost "serious." The book is interesting not only for geologists from scientific institutes and universities, but also for those in geological practice and for young people. Along with them, geologists' closest colleagues—mining engineers and geographers—as well as anyone who loves and appreciates good, fresh humor, will also be able to laugh heartily. Some of the "jokes" are directly related to a (still fading) era—the socialist era. We do not consider this a disadvantage, but on the contrary: let us remember where, when, and how often we were funny.
