Both of these were when i was an undergrad, there was a school bench press meet, and this dude had 330lbs on the bar and it was going up easy so his spotter wasnt ready, and it fell back right on his neck about midway up. He was squirming, but suprisingly didnt get hurt. Another time my buddy was squatting 600, and when he went to re rack the shit, the guy on the other side of me got the skin inbetween his thumb and finger pinched in the bars you rack it on. It took a second to realize what was making him scream, then we picked it up and his shit was bleeding everywhere.
