When I attended a UFC in Las Vegas a couple of years ago, Mike Tyson was sitting down in the first few rows on the floor. This stupid punk behind me kept yelling trash at Tyson and flipping him off. Finally Tyson got fed up with it and started walking up the stairs to where I was sitting. The kid got up and took off when Tyson was about 10 rows away and didn't come back until half way through the UFC.
I was worried that Tyson was going to think I was doing it too and was coming to kick ---my bottom---, but luckily he didn't.
