I've just watched the first two episodes of a comedy on BBC3 called Summer Heights High. You just have to give it a try; it's one of the funniest things I've seen this year. It's an Australian "mockumentary" set in a high school, but the characters are so wittily observed. I especially like Jonah, the 13 year old swearing hard nut with a reading age of 8. Most schools have at least one Jonah, even if theirs isn't from Tonga.
Try to catch it if you can!
