Weird concert experiences

[njdss4]

I've had a couple of weird concert experiences. At an Evanescence concert this man who was sitting next to me started doing air guitar yelling out that it's his birthday and he's gonna party. It was hilarious. Then he proceeded to take his shirt off and by the end of the first song, there was 5 foot span between him and the closest person. Then at a Garbage concert an entire section of the audience started screaming "VD! VD! VD!" (venerial disease)(sp?) and they actually got Shirley Manson (lead singer for Garbage) to talk about how she wrote a song about her old boyfriend that gave her VD. Anyone else have weirder stories to tell?
