These anecdotes are not really funny, but most unusual and worth reporting.
1. Saw REAL TV last night where a powerlifter was going for 575 and got it, but missed racking the weight while the spotters were asleep. Dropped it on his chest. I actually gasped out loud watching it. I thought it would have killed him, but not even a broken rib.
2. Saw a guy doing lateral dumbell flyes with weights way too heavy for him. He was using body momentum to throw them up. He had no control whatsoever. On one rep the weights came down too fast and he clacked his nuts from both sides with 30 pounders. Yeeeooow!
3. One time I was trying to do a 1 rep max on leg extensions. I have the rack, plus two 25 pound plates on the front. As I am getting psyched, some joker pulls the pin to use in another machine. Now with only 50 pounds instead of 250, the plates come flying off with all the extra force and smash one of the giant wall mirrors. Of course I get all the stares. Never found out who did it.
4. Saw one dude doing cable lat pulls with around 200 when the cable broke (lawsuit heaven!). He pulled the bar so hard into his head he knocked himself out.
