California Surfer Films Pants-Pissing Moment a Great White Shark Swims Under His Board

According to the YouTube description here's how it all went down: 

Mike Durand of put on his GOPRO Cam/helmet and went in search of Great White Sharks off of Manhattan Beach, El Porto. After spotting one with the cam off he thought is day was over. Number 2 swam into the picture and ended up scaring the shit out of him. It's all fun until someone loses an eye, (or leg).
