A good chunk of YouTube is videos of skateboarders performing tricks. Unless you are deeply entrenched in skating culture, or the trick is amazing or death-defying, watching such clips is generally a boring waste of time.
And the video you are about to see, in which Dutch skateboarder Jaasir Linger performs a rather mundane trick on a park bench, starts off routine enough. However, if you stick with it for about 17 seconds, you will get your just reward. Keep your eyes on the bus in the background.
