I'm not sure if this would be everybody here's cup of tea, but I found the first series of this British sketch show to be pretty entertaining. It's basically sketch comedy performed by a group of children (adolescents really, most of them are teenagers). The most well-known member of the cast would probably be Will Poulter , who was in the movie "Son of Rambow". Here's a sample sketch to give you a flavor of what the show is like. There is a little bit of cognitive dissonance involved here, in that in this sketch you have children playing teachers who are teaching children, but the actual content of the sketch is pretty funny:
There's a new series starting on Monday in the UK.
