The Washington Post: "Shark bites man. Man punches shark in head."

The shark picked the wrong guy to mess with. This occurred at the Outer Banks in North Carolina:

     A shark bit Patrick Thornton.
     So Thornton punched it in the head. [emphasis added]
     The 47-year-old Charlotte man’s ankle had just been bitten by what he thought was a crab off North Carolina’s Outer Banks, he told the Virginian-Pilot. Then, he saw the 5-foot shark nearby.
      “I yelled, ‘Shark! Shark!'” he recalled.
     According to the National Park Service, the attack took place Friday morning, where Thornton had been swimming with others a mile north of the Avon Fishing Pier off the coast of Avon.
