Sayonara, Zetsubou-Sensei 3: The Power of Negative Thinking

Sayonara, Zetsubou-Sensei 3: The Power of Negative Thinking - Koji Kumeta This manga is so random (which is my favorite kind of manga, TBH). The chapters do not relate to each other (episodic manga is called? or something like that). It is still insanely funny, but this time most of the chapters did not make any sense to me at all. There are more notes to read at the end of each chapter, there are thousands of lists (although I laughed in several of them) and the stuff the Sensei and his students do are so random.
