Now that the gunman who opened fire on the Virginia Tech campus was discovered to have been insane, it may soon be a lot tougher for the mentally ill to purchase a firearm so easily. Which will be very bad news for the erratic Andy Dick if he ever finds the need to be armed, God forbid. Although, really, he does all right by himself without a gun. For example, just the other night at the club Snitch in Manhattan he did some Dick-style damage. According to a witness, Dick grabbed a waitress’ boobs and dug his nails into her neck, then poked her in the ear “really hard.” Then he stuck his hand down the doorman’s pants. Earlier in the evening, at the Cutting Room, he lit his receipt on fire. You know, we can almost – almost – understand the receipt ignition, the boobs grab, the neck dig, and the junk fondle, but we’re scratching our head over the ear poke.(Page Six)
