Don't know how we could have missed this one. The voices that, thanks to Hollywood, you know better than you know your own--Don LaFontaine, John Leader, Nick Tate, Mark Elliot and Al Chalk--all assembled in one car and trying to out-vox each other. Classic.
Update: Updated the video links so they should work now. Thanks to MrHaydel on Blue Dot for giving us the credit and providing the updated YouTube info.
