If you like comedies about misfits, then Waterboys (?????????, W?t? B?izu) is for you.

Its about a group of Japanese high school boys who decide to do synchronised swimming.
Its quite funny and lead to a sequel of sorts, Swing Girls (no not that swing) about a group of Japanese school girls who are the class misfits. Instead of swimming, they create a big band swing group.

What I liked about both movies was the positive outlook on life our heroes had. Even though they were the misfits good things came to them in the end.
