Pull Your Gym Shorts Down or I'll Do it for You

Everyday I have P.E. and the students in there have a weird fascination of sneaking up behind someone and pulling down their gym shorts. I only have one question, WHY? Especially boys pulling other boy's gym shorts down. I don't know if it's because they like seeing butts, no matter whose it belongs to, or because it's the only time of day that their victims are wearing something that is easy to pull down, or perhaps it's because they're secretly gay and this is the only way to get "some action" without people thinking they are. But wait... that can't be it because just today a guy had done it to a girl during gym class, and everyone saw that she was wearing a thong and they all threw up at the sight of it. But the point is, pulling down any one's gym shorts is wrong, because it may cause a huge catastrophe causing people to lose their eye sight and cause a lost of appetites for many days on end. So pull shorts down wisely if you must do it. Thank you.
