I was standing in my kayak, and made a very stupid flip behind me over my right shoulder to a piece of cover I missed. Got bit, and made the most awkward hookset ever, didn't hook the fish, and decided to jump out instead of rolling my kayak over. Water wasn't over my head so it turned out alright, continued to have an excellent day afterwords.
My friend slipped on some ice in February last year while goose hunting, and swamped his waders. We were a quarter mile from the tractor we used to get there, and a mile from the house with 15-20" of heavy wet snow on the ground. I was very worried about him but luckily we made it back to the house and he warmed up.
