Some people aren't born to skateboard. Take the guy in the video below, for example. He sucks at riding a skateboard: that's strike one. He sucks at falling: that's strike two. And he's a crybaby: that's strike three.
As the video starts, you can see the skateboarder go up a ramp. However, things go wrong when his skateboard sticks at the top of the ramp. The guy ends up belly flopping to the ground.
