They looked at this video which is OBVIOUSLY a joke, and they took it seriously. Obviously they know nothing about skating/surfing, or they would realize that skating for 4 seconds across a tarp is nothing like surfing at all. It's just like skating in a straight line but with a visual effect, being the tarp.
