After watching the 25th Anniversary Rock n' Roll Hall of Fame concert on HBO I have come to the conclusion that they have secretly replaced you regular bumbling, stammering, stuttering, burned out Ozzy with a reasonable facsimile Ozzy.
I submit to you EXHIBIT A "America's Got Talent" with judge Sharon OSBOURNE!
Sharon saw the Crazy (gravy) Train leaving the station and acted impulsively in order to save the lifestyle of which she's been accustomed to for, low, these many years as Mrs. Prince of Bleepin' Darknesss.
Impossible! Blasphemy! You scoff.
Watch the video below and "HA!" I say.
