Arguably the most famous moment in skateboarding history was when Tony Hawk landed a 900 at the X Games back in 1999.
The trick helped catapult skateboarding and the X Games into the mainstream, and cemented Hawk's place as a legend in his sport.
It's hard to believe, but Monday was the 17-year anniversary of Hawk's famous 900. Now 48-years-old, Hawk thought he could still pull off the trick.
So he decided to find out.
It sure wasn't easy, but neither was the first one. In fact, the 900 Hawk pulled at 48 looks almost identical to the one he landed 17 years earlier.
