While you're planning your weekend, I want you to consider skipping the ballgame/movie/park. Instead: strap on a helmet, sit on an airbag, and deploy it as your friends watch and laugh. Faceplant? No, no. That's a neckplant you're watching.
Some NSFW language (understandably) and a loud BOOM here, so head's up if you're at the office. But don't turn the volume down too low; otherwise you might miss the quote of the day. You know, the one about how rich people spend their spare time... uh... exploding airbags. [YouTube via Geekologie, Jalopnik]
