A few recent ones.
Dudes squatting like 250+ but only going down about a few inches (not to mention putting the safety stop above elbow height). They look over at me only squatting 180, but going past parallel. They look at me with a smirk, then they try to go deeper only to start wobbling like a spaghetti noodle once they go NEAR 45 degrees then go back up. I just laugh.
Another along those lines. A group of high school kids were doing overhead presses with one foot WAAAAY out in front of the other and with around 135+ on the bar, but their arms weren't doing ANYTHING...their whole torso was going down while the bar stayed pretty much exactly in the same position. I had to bite my tongue so hard not to laugh.
I'll take form over heavy any day.
