Years ago I was steelhead fishing on the Oregon coast. There was a nice layer of ice along the edge of the river. I ended up getting one steelie and was cleaning it when I got to thinking, boy this fish sure has a lot of blood in it.

Well it turns out I had chopped a good way through my finger when I was taking the gills out. My hands were so numb from the cold I didn't even feel it. I wrapped a handkerchief around my finger and it was almost completely soaked thru by the time I got home.
