Nitro Circuis barbie car jump

Wanna see something really crazy? How about some double and triple flips, with riders and pilots mounted on all sorts of crazy contraptions? We've got some of the usual suspects, dirt bikes, wheelchairs, pink barbie cars...

Yes, we said pink barbie cars. You know – the plastic kind that little girls from your neighborhood ride the sidewalks in.

The event took place on June 5th, 2011, at the MGM Grand Arena in front of a live audience in Las Vegas. Hey, Travis Pastrana and the rest of the motley Nitro Circus crew sure beats Celine Dion, right?

Among the world-firsts made or at least attempted during the event were a synchronized double back flip, a three-person back flip and a double front Superman flip. If you don't know what any of that means, we suggest you check out the video after the break.

Oh, and if all that wasn't enough, Travis Pastrana also used the live event to propose to his girlfriend, X Games gold medalist Lyn-Z Adams Hawkins. Video of that blessed moment can also be seen... you guessed it, after the break.
