Take an airbag out of a car or truck and secretly stash it under a couch cushion. When an unsuspecting victim sits on the right cushion let the airbag off. Airbag's explode at over 200 mph, this will send the victim 4 to 5 feet in the air and will feel like someone ripped him a new asshole. Hilarity ensues this will be a classic video, try it out let me know what you think. Then get me on a plane to L.A. I wanna party with you.
