William Zabka is on Twitter

Actor William Zabka, most famous for his prick villain role in “The Karate Kid” and not so much his Oscar-nominated short film from 2003, has been tweeting for a while. But it wasn’t until comic Patton Oswalt outed Zabka’s online existence last week to his million-plus followers that word finally got out.

Oh, to have Patton Oswalt as your press flack. Zabka seemed appreciative enough.

But the “failure pile in a sadness bowl” coiner didn’t stop there. Oh noooo. Oswalt sat down and wrote an entire piece of “Karate Kid” fan fiction devoted to the aftermath of what would become Zabka’s Johnny “Sweep the Leg” Lawrence’s miserable post-adolescence. (No spoilers. A must-read.)

Zabka’s response? A page torn right out of the Cobra Kai handbook for mouthing trash:

If you need a refresher on the highlights of Zabka’s Reagan Era run, this fun-loving homage to the “80s blond jock asshole” will get you up to speed. Also, a nice primer for Oswalt’s fan fiction.
