It’s easy, now that the Black Label Society have released an official Zakk Wylde Halloween costume.
You can order that nonsense here.
Or just take five balls of brown yarn, glue ‘em to your kid’s chin, toss a BLS cap on his head and put a fifth of Jack in his hand.
That, too, would get the job done.
Then, once you are dressed as Zakk, go around threatening to break people’s legs but then don’t break them.
As pictured, you’ll see the costume comes with a fake beard and beanie combination, plus a vest.
I’d rather go as Mr. Schoop from “Summer School,” but that’s just me.
