There's a great column in SI recently about how to behave at live sporting events. This pertains to concerts as well, and in my opinion, most of what Steve Rushin said should be basic knowledge and common courtesy. The two that really grind my gears are the people that don't stand during the pledge of allegiance as well as people who don't give foul balls to young kids. I want to go up to people that don't stand and asks them if they are sitting down in protest of the military, and if they'd be willing to trade places with our soldiers. And people who fight for foul balls? Seriously. Home runs are one thing, but once someone gets a hold of the ball, give it to the nearest kid. It's the manly thing to do.
