This has me shaking my head! Here is the setup: It’s three guys on a golf course, and one of them is the surfboard in this video. So, the surfboard guy is lying on his back in the grass being pushed by a guy driving a golf cart. A third guy is the surfer.
He’s literally standing on the surfboard guy’s chest and riding him while pouring beer into the guy’s mouth, and they’re all moving forward on the smooth grass.
