Some of the funniest stuff I see has to be during the resolution season. I see all these new faces at the gym, most of them either being 14-18 males being too skinny trying to be like ronnie coleman. They usually come with their crews too. Do couple of bench press then puff up like a freaking rooster or something.
Then there are those old people/hippie types, they try to do their "out of the boxes" workouts. Basically some weird shit that no one has ever seen before. Story time:
I was doing bench press, after finished my set I sat up, low and behold I see this middle aged, decent sized woman trying to do splits to stretch her legs with her ass facing me, and her back bent parallel to the ground. I don't know what happens next but she basically trips, and on the process takes about 4-5 steps backwards and falls right back on bench I was sitting on. She almost took out my dick during that whole escapade too. At first I just smiled at her, she smiled back, sort of in a embarrasing manor, when I saw that, I started to laugh really loud. She turns RED, and walks away really fast.
