Alright, it's not really that great but I'll tell it anyways.
So two years ago this girl (who is currently in jail, actually) and myself would always get on this one forum during yearbook class. She always pretended to have a "crush" on this one teacher...and there was a "hot teacher" thread. Well, it got pretty wild. We both made aliases, and it got out of hand fast. The teacher was my neighbor, so she went as far as saying that the teacher's wife was a lesbian, and when she'd leave she'd sneak into his bedroom, etc etc, then hide in the closed when his wife and him were doing it, etc etc. Haha, wow, thinking back it was actually hilarious.
So anyways, we weren't the only two people who found it funny. Other kids in the class got in on it too.
One night I got a phone call from this weird kid that said the teacher knew. WTF. This teacher and I were relatively tight-- he was usually a cool dude-- but earlier that week I heard him talking about persuing a lawsuit against one of his students for slander. At the time, I thought nothing of it, because I was a suckup, and we were tight.
Not so. Although I didn't actually say any shit about him or his wife I egged this girl on pretty hardcore. I called my teacher that night and he was PISSED/disappointed. I felt so shitty. I had a lot of extracirricular activities with that teacher and from that year on it just wasn't the same. I wrote him a long-ass apology letter (it was fucking epic, I basically wrote it so he wouldn't press charges), and things kind of went back to normal.
So moral of the story is don't be a dumbass.
