But he always seemed like such a wholesome boy...! Us reports Steve-O previously was checked into Cedars-Sinai's mental health ward in L.A. in March, and plead guilty to cocaine possession in June.

The stunt-prone gross-out artist is locked up again, but has turned his lemons into lemonade, and is giving out pearls of wisdom on his blog: "Everyone's going to make their own decisions in life, but nobody needs to make the same mistakes I made."

Thanks, Steve-O! A whole generation of kids would be lost without you!
