I've stuck a hook in my thumb once when the fish flopped
around and I had my hand near its mouth. Nothing like having a 30 pounder flopping with a plug stuck in it's mouth on one set of hooks and the other set of hooks stuck in your thumb.

The "string method" worked and I went right back to fishing.
I took that fish home.
