To read this work, you need special preparation: tie your stomach with something so that it does not burst from laughter, strengthen your lower jaw with electrical tape so that it does not collapse from laughter, because without it it is impossible to read this work. Maximum density of “chatter” and jokes on every page, which brings incomparable pleasure. Even the biography of Professor Donda, the story of his birth makes you cry hysterically, not to mention his deeds. It makes no sense to retell anything about the professor, because no one can do it better than Lem himself.©ozor
