Tony Hawk does a 900JUL 21 2010

At 42 years old, with the smile crinkles around his eyes to prove it, Tony Hawk can still do a 900 on a skateboard.

According to Wikipedia, Hawk is one of only four men in the world who have done this trick (he first did it in 1999). He announced on Twitter that he'd done the trick -- "P.S. I made a 9" -- and on his way out of town left one of his boards at the airport for a lucky fan to find. (thx, dens)
