If you end up on jackass, please, for the love of god, don't be stupid enough to bike, skate, rollerblade, drive, or otherwise travel into oncoming traffic in hopes of getting air of a car's front bumper. It has been my long experience of seeing and/or experiencing car and/or other accidents that bumpers tend to force one DOWN, despite the nearly obvious defiance of the laws of gravity, aerodynamics, and inertia. I would hate to miss your posts in the future because you were too injured and/or dead in the future to type them.
