That was one of the weirdest things I've ever seen on a racetrack. I love how the one rider is freakin' out because he can't figure out how to get them to stop. He's probably counting the $$$ burn up as it happens.
Gosh, that is funny. I did a quick google search and found a site where you could mute the sound and play the Benny Hill music along side the bike video. The video alone is worth watching, but as Hos said the Benn Hill music is a perfect backdrop.
