Knock on wood!!! I've been pretty fortunate here! A few times while releasing a fish from the teaser I've had the fish drop onto the plug and pull the teaser into my hand but where I've been fortunate is that the barb has not penetrated beyond the skin. I have been able to drop the hand almost but not quite as fast as the fish pulled the plug down...
I wacked myself in the head with a 2oz jig once while trying to unfree it from a weedy rock - that hurt. Not hooked but the jig was bad enough...
My biggest problem is falling off a rock and landing, soaked on another rock. I still have some scrapes and bruises from one such night a couple weeks ago <img src="/Images/biggrin.gif"><!--e7-->....
