I've said it before, I'll say it again. If you want a good, albeit REALLY dirty anime, watch golden boy.

Ahh... Golden boy. If you've seen it, you'll understand. It's one of the funniest anime's I have ever seen. And I have seen ALOT of anime. It does have an older style of drawing though. There is also a manga, I haven't read it, so I don't know if it's as funny. But there is a swimming scene in.. I think episode 3 that's literally had me ROLLING from laughter. Anyway, go.now. Watch!
