Never a self hook, but when i was younger and first getting into fishing, i was on the shoreline and wasn't paying attention to my surrounding all too well, my friend passed behind me at the same time that i was casting and SNAP! i thought i had snapped my 20 lb test and crankbait on the picnic table behind me, but instead it was the head of my friend. he had to get rushed to the hospital and have it removed, three hooks all past the barb, they had to make exit holes to push them out. i gave him a bunch of my lures as a "im sorry i hooked you in the head" but i still feel like crap about it to this day.
