Ex-New York Knick Stephon Marbury may not be streaming his descent into insanity online with his reality show anymore, but he's still acting crazy as hell. Steph showed up to Madison Square Garden for the Knicks' home opener Saturday night and sat on the front row filming the game. Doesn't sound that crazy does it? Well, how about the fact that he'd swiped somebody else's seats and was standing up blocking the view of other spectators? When the ushers came to tell him to sit down, they checked his tickets and told him to go to his correct seat. Steph got embarrassed pissed off chose to leave instead.
