"School of Rock" Kid Guilty in Taco Bell DUI Caper

Joey Gaydos Jr. -- the guitar prodigy from "School of Rock" -- has pled guilty to a misdemeanor impaired driving charge and could actually do some time in the pokey for his crime. WWJBD?

Cops busted Gaydos as he was leaving a Taco Bell at 2:40 AM -- which as far as we know is conclusive proof someone is wasted.

The 17-year-old actor faces up to 93 days in jail. He'll be sentenced in April.
