Bakabon

バカボン

A young boy who enjoys causing mischief, especially with his Papa. On the inside, though, he is a kind boy and works a part-time job as a shoeshine in order to buy his mother a birthday present. He is known for not wearing pants underneath his kimono. At the beginning of the series he attends Boumou Eggplant Elementary School, but by the fourth anime it has been renamed Bakada Elementary School. (source: wikipedia)
