Picture Show: Ozzy Osbourne Signs Copy of I Am Ozzy At Barnes and Noble

As promised, Ozzy Osbourne, the prince of mother-effing darkness, stopped by the Northwest Highway Barnes & Noble location in Dallas to sign copies of his new autobiography, I Am Ozzy, on Saturday afternoon.

It was quite the scene, too, as photographer Spike Johnson found out while shooting this slideshow of pictures for your viewing pleasure. A few die-hard fans even camped out for the chance to meet the legend in the flesh.
