I went with some friends to Jets/Giants preseason game back in '88, and it went something like this:
A fight broke out in the section next to us! Almost turned into a brawl. Then we heard a huge comotion behind us. Some drunk lady on the upper deck was pouring beer on the people below. There was lotsa shouting and name calling until security took her out. We all cheered that she was finally gone.
Then my friend pointed to a spot about 10 rows back and to the left of us. Some freaky looking guy wearing a black body suit with a little chrome hammer hung on his belt was dancing around near the aisle. He started blocking the aisle while dancing when some hot ladies tried to pass him. Some fans took exception to this, and guess what? Another fight! Mostly just pushing and shoving.
That's when another friend tapped me on the shoulder and said: "Hey! look behind us! They're playing a football game here too! LOL
