Remember that friendly shark in 'Finding Nemo' who swore never to eat fish again in his life? They found him!
And by "they found him" we mean, someone took a picture of a shark whose horrifyingly sharp teeth form a large, menacing grin.

Okay, the smile does look a little goofy. A retiree named Kenneth “Wayne” MacWilliams apparently captured this off the coast of Florida and shared it with Caters News Agency. Apparently this is a lemon shark, the "friendliest" of sharks.
