Burn his book bag. With his stuff in it. And video it. Then send it to him. Mean while, you take every book, and roll paint over ever page. Then coat his locker in a thin layer of glue through his locker, letting him set all his stuff in it, and have it all stick there so he must damage it to get it out.
And for good measure, be sure to sure to place the rotting carcass of an animal in it, preferrably in a place where he wont see/be able to remove it.
And finally, the daddy to end it all, as he's walking down the stairs, be sure to sling your backpack into his knees, sending him hurtling down them while he can only look at you in a pained stunned silence.
It all works best if you can manage it in one day, which, while difficult, is not impossible, and is EXCEEDINGLY rewarding if you can.
... or just slip a maxipad in his backpack or something. You know, if you're a newbie.
