Top Gear had an episode with Jeremy doing that in an Irish sewer system with some little car.
Bliss, while I certainly appreciate the beauty, let's make that pic the exception rather than the rule. Got some puritans worried about kids coming to the Lounge on a Cobra site (rather than cleaning their rooms or playing R-rated games on the electronic device I guess). Next thing you know it'll be Fred's jiggles and my butt being called into question...and that I'll take personal. Your help in that regard would be appreciated.
