I got a couple.

In-between the ages of 10-14 I would camp for several days down at Twanoh State park during the summer. We would catch all different kinds of fish off the state park dock there, and every bullhead would get cut in half then thrown back to chum the water for Sharks that night ( just a dumb kid thing to do)

We would stay out on the dock late at night and catch some nice sand shark, some up to six feet.
Once I was pulling a big one in, got him on the dock, and proceeded to pull my hook out of his mouth when he turned and nailed my finger good. 18 stitches the next morning up in Belfair.

I also got nailed as a young'in by my grandfather while walking up behind him while he was flyfishing. His fly buried itself into my skullcap. had to do the old push it out and cut the bard off, then back it out trick. OUCH!
