So much so, I want to turn you on to it too.
The presenter is Hans Rosling, whose TED talk on Global Population a few years ago has been a hit ever since it was released on the 'net. I can only assume someone at the BBC saw the TED talk and said We should see that this guy can do with an hour and a production budget. The Joy of Stats is the happy result.
You can watch some scenes from it courtesy of The Open University. Unfortunately, unless you already have an account on uknova (which can be hard to come by), I don't know where you can download it.
I plan to watch it again sometime in first half of January, and would be happy to make it a social event if people are interested.
