Frankly?
I'd go to the principle and TELL him to do something about it.
Don't ASK, TELL
You do know the difference right?
TELL him this is "Bullying" and if he doesn't stop it, that it WILL stop and it's likely that he won't like HOW it stops...
And you'll make it a point to see that whatever you are forced to do will reflect on HIM.
Being honest? I'd tee up the MoFu's knee with a golf club.
I'd do it while he was with a group of HIS friends.
Just walk up cool as a bag of frozen broccoli and let him have it.
what do you do when he's down and crying like a little girl
and screaming he's "going to kill you for this"?
whack the crap out of his other knee...
some people are slow learners, if he says anything other than
"please don't hurt me any more" after the second knee? wind up
and try to kick his nuts for a field goal.
I graduated highschool in 1979 and you really don't want to know
what I'd do today if I caught someone messing with my well worn ranger...
I've had people wandering around my yard...
My response was to string barbed wire ankle high....
I won't discuss what I smear on the barbs...
