There's a man in a red shirt and a checked shirt over it, standing in a park.  He throws a rubber tire on the ground.  He is standing near a park bench with a skateboard in his hand.  He is demonstrating how to do stunts on the skateboard by jumping up on the park bench.  He repeats the same stunt over and over again.  He falls off the skateboard a couple times but is successful most of the time.  Then he holds the skateboard in his hand as he talks while pointing to the bench.
