Trevor Jacob is a double threat, at least. The 18-year-old pro snowboarder recently pulled off an incredible move on a skateboard.

While passing through Pennsylvania on a bid to skate across the country, Jacob attempts a move that he describes -- and that certainly looks like -- a double backflip on a skateboard. Not bad for someone who "wasn't even planing on trying it." Of course, for a guy who has already literally hopped a train this might not seem like that big of a deal.

Despite the impressive nature of the trick, there is apparently some doubt over how it should be classified. Whether or not it was actually a double cork, it sure seems double awesome.

Maybe not a true dbl cork, but snowboarding tricks coming to skateboarding still jaw-dropping:
