I've been bass fishing for about a year now, and I've had more painful hook experiences in that year than I care to remember. Thankfully, though, none have got very deep. The worst I've had is when a friend and I were fishing the bank together from a small spot (bad idea!) and he cast an EWG into my head. It didn't get deep but it still hurt bad. The same friend later cast another EWG into my arm, that wasn't as bad, but I don't fish close to him anymore! I've never had a Bill Dance moment where trebles got through my nose or anything like that.
My personal least favorite are when hooks get stuck in my clothing or my carpet. I always have to cut them loose, and I've ruined several nice pieces of clothing.
One instance was when my brothers and I were walking back to our car after fishing, and my little brother refused to put his lipless crankbait (never give a ten yr old a lipless!) in his hook keeper and was swinging it around and guess what? It got stuck in my shorts and my older brother had to cut it out with his pocketknife. I liked those shorts.
