Surfing with sharks: Oregon man claims he rode the back of Great White

Oregon man Doug Niblack was surfing off a popular surfing spot when he was knocked off his surfboard. He somehow ended up on his feet and regained his balance before realizing he was on the back of a 12ft Great White Shark. After a ride lasting a few seconds Niblack fell into the water and quickly paddled back to the shore.
