What was the best "karma is a bitch" moment you have witnessed?

I grew up in a tiny town in the bible belt, just one small public school of K-12. I always knew I was "different" and there was this other kid I met in kindergarten who was "different" too. And, for whatever reason(I can pop-psy a few reasons looking back now), he hated my guts. I tried to make friends with him several times over the years and he would only fake being my friend just to fuck with me. He made my life a living hell and enjoyed every minute of it.

For example: one time in middle school when the history teacher, who was also a pentecostal preacher, decided to entertain the class with the story of how some gay guy tried to proposition him while he was in the army. Of course the moral of the story was that gay people were disgusting evil perverts who were all going to hell, ha ha ha. While the whole class was laughing along I was miserably sinking my head down on my desk under my arms, and to fight my own misery I stupidly whispered out loud to myself, "I don't think gay people are evil." And, of course, my nemesis was sitting next to me and overheard. I glanced over to see a look of pure orgasmic ecstasy on his face, as he shot his hand into the air and started waving it while bouncing around in his seat. "MR. FUCKHEAD. JHM DOESNT THINK GAY PEOPLE ARE EVIL!!!" The room went dead silent. The teacher looked like he was going to have a stroke and everyone turned to look at me as if I had suddenly ripped off my human mask and revealed myself to be some kind of alien-demon. Thankfully the teacher wasnt a 100% shitball and he just quickly changed the subject back to his actual job of teaching history.

Another time he passed me a note in class telling me I "talk like the girls from showgirls", apparently referring to a lisp I had developed from wearing a huge godawful retainer. I could only wonder what his excuse was...

Karma: Fast forward to senior year. My nemesis was "dating" a rather large but sweet and naive girl, when somehow she found out that he had been secretly going to the gay bar a few towns over with a fake ID, and hooking up with 30 year old men. Seven of them, so far. She did NOT keep it a secret, in fact she stopped being a sweet girl with a flick of a bitch switch and pretty much screamed it all out at the top of her lungs in a holy righteous rage for everyone in a 10 block radius (the whole town) to hear. He even tried to stay with her saying "I still like you, we can still be boyfriend and girlfriend" as if this was elementary school and they were just playing house. That just made her louder.

Yearbook voting rolls around.. and guess who got voted "most changed"(though he hadn't changed at all since kindergarten), and got to walk out during an assembly to accept his "award" with the entire high school of rednecks there laughing, jeering, cat-calling and clapping for him?

I found out later through facebook that he became a "gay youth counselor"... I wonder if he tells the kids about his youth, but pretends he was me?
