My favourites are of course the infamous, Way of the Master series. Preaching Evangelical Christians at their best!
Simply type in "Way of the Master" into Google Video.
My favourite, is the one linked in another thread about atheism...
I also love this video: http://video.google.com/videoplay?do...200&q=top+gear
It was made by Top Gear and basically is the turbine of a Boeing obliterating two cars. Very good watch.
