The UK shows have had the announcer replaced with some British guy who gets his jokes from reject Christmas crackers. Not sure how it is in the US with the original.
They what? That's unforgivable! When you think about it, the narrator is almost the biggest part of the show. At least, he's the one you hear the most. I can't imagine the show without him!
'fraid so, they have the narrator convert all the Imperial units in SI units as well, for no particularly good reason.
On the totally hacked about BBC2 version he also has to fill in all the gaps after they have hacked out Adam and Jamies conversations about what they are doing.
Thank goodness for bittorrent...
