Exceptionally Uncaught

I've just been watching the Mythbusters. It was an episode I'd already seen, but what was interesting was the over-voice. The biggest mistake they made with the Australian version of Mythbusters was just repeating exactly what the American announcer said. The UK version doesn't do that - they've actually gone to the trouble of "translating".

I'm now wondering how many other versions of Mythbusters there are in the world, and what they're all like...
