Flexing your ring finger
I had this one guy, who enjoyed being a part time bully and part time neutral to me.
To say the least he was annoying. He'd take the liberty to hide my backpack, borrow my books without consent, doodle scandalous stuff on my notebooks with a pen and yada yada.
So one day, I was showing this cool trick I learned on an anatomy program on the TV to a couple of classmates who used to sit around me. The thing was that you can't flex your ring finger upwards if you put your middle finger under the palm (try that)
We were all kids, and soon everyone in the class started staring at us weirdos looking laughing at out hands. The bully noticed it too, and came near to inquire about this hand stuff. I described the trick and he was impressed.
And then,
I saw our teacher walking up the corridor, just a couple paces behind the class door. So, I asked him (the bully) if he wanted to see another trick and to that he nodded a big yes.
Cool,
What I did was, that I grabbed his right arm by the thumb and put it on my throat right above the larynx. Then I quickly shifted my grip to his wrist. He without batting an eye, asked what I was doing, but then I started beating the desk with my other hand and made squeaking noises while pushing his hand against my throat harder with every turning head. And voilà! Every one in the class (including the teacher) thought he was smothering me.
After a few ifs and buts between him and the teacher, he was summoned at the principal’s chambers, from where, later he was sent home, where presumably judging from the look on his face for the next few days, he was beat to crap by his folks.
And after that, never was I ever bothered by anyone in the school.(^^)
