The worst I remember was when I was working in a pharmacy years ago during a finals game in which the Jazz were at home against the Bulls.  I had the radio on and was dying to see the game.  In walks a cougar (attractive 40 something lady) decked out in Jazz gear to the point you would almost think she was one of their cheerleaders. (She looked to be very fit)

She spent a good half hour looking over the cosmetic department while the Jazz were playing one of the most important games in their history. 

But it might be true these fans simply don't get the PAC12 channel I heard a lot of complaining about that this week.
