<human>: Can you condense the text into three sentences or less?

When I was about 15, someone in my grade leaned how to do the sleeper hold from his boss and taught all of his friends at school. It wasn't long before every guy in my year new how to do it and it was happening relentlessly. Guys would sneak up behind each other and choke each other out. A few were caught doing it and got in a lot of trouble, but it didn't stem the epidemic.

I was always pretty quick and no one had managed to get me yet, so I had become a prime target. One day I'm talking to this girl and all of a sudden a huge black arm wraps around my neck and I hear my friend Gareths goofy "haw haw haw" laugh. I struggled to break free, but I was small and weeny and Gareth was a **huge** islander, so there was no escape. 

I'm fighting, trying to pull his arm away with both my hands but then I black out. I wake up with my face covered in drool, no idea where I am, I'm still babbling and there's a crowd of really scared looking people standing over me asking if I'm OK. I get up in a haze and stagger around for a few seconds like a newborn giraffe before I get my bearings and remembered what happened. I look around for Gareth and he's 2 football fields away, running for his life screaming "I killed him!" and crying.

Apparently when I blacked out my hands didn't fall, but stayed gripped to Gareth's forearm, so he didn't know I'd passed out and choked me for way too long. When I dropped I had a severe seizure, foamed at the mouth and babbled incoherently until I woke up. Gareth was dead sure I was done for and was already on the run for murder before I woke up.

After that the sleeper holds became *much* less frequent and nobody dared do it to me in case I died.
<bot>: All the dumbasses at my high school were doing sleeper holds on each other. Someone does it to me for too long. I have a seizure. Friend thinks he's murdered me and runs for his life.
