Don't know if this counts....I know its not what you really meant....but...........a scar on my foot from being 'stung' by a stingray on the beach at Tampa.

Was there with the whole family - and we were going for a swim in an area that had many other swimmers and seemed 'safe'. I had read up on the warnings and kept telling family to shuffle feet like me. Suddenly I was dinged and shouted out - they all thought I was joking...until I managed to raise my foot above the water line and everyone saw the blood sputing out !! And it really hurt !!

Quite an unforgettable souvenir.
