I hate the 100's. quick story, Gym I use to go to,, a guy that would come in the evening would use the 100s on the leg press machine and then leave them on there. The next morning all the women would be pissed because they couldn't take the weights off. I found out what this guy was doing that morning. Being an Ahole of course. He was the only one using the 100's. So I took each hundred and put them face down at two opposite corners of the gym. The next day they were on the leg press machine again. I repeated my action for about 6 days, and I finally got word back that he got the message.
