back in 1991, my first month in the gym, i was doing monster behind-the-neck presses with a dime on each side. my friend challenged me to an even more brutal weight of 75 lbs for my last set. he gave me a lift-off, i did 4-5 reps, and then got stuck at the bottom. he wanted to take the bar from me, grabbed it (standing behind me), and i simply let it go. of course he could not hold it and the bar flew down, hit the bench, and crushed my friend's index finger in the process. he had a crushed bone and a damaged tendon. the tendon was reattached surgically but until today his finger looks a little bit crooked.
