You guys who are afraid of sharks and the ocean would just LOVE to be sitting out on a surf board and have a dolphin rub up against your leg for the first time eh?
lol...in my younger days, I surfed a little when I lived on Hatteras Island. The dolphins are very playful when you are in the water and lots of times will come up and "rub" against you or "nudge" you with their noses.
Needless to say, that's not for the weak of heart or clean of shorts.

First time it happens, if you don't know what's going on or that it's normal, you will pretty much shit yourself. lol...
