Sayonara, Zetsubou-Sensei

This episode begins with Kagerō Usui lamenting about how he never gets noticed by anyone, when he nearly gets run over by a truck driver who does not notice him. He runs into Nozomu in the shadows, who begins to talk about how some people are destined to be overshadowed by others, no matter how hard they work. After several humorous examples to illustrate his point, Kafuka brings up the merits of being in the shadows. Meanwhile, Kagerō continues to be unnoticed by everyone. The second part of the episode has the class undergo criticism training. A strange man enters the classroom and begins to launch various insults at the students. Kagerō continues to be ignored until a divine wind blows away his hair, revealing his bald head and allowing everyone in the class to see him. He fears that people in the class will begin mocking him, but Kafuka suggests that Chie insult him instead, which he seems to enjoy. (Source: Wikipedia)
