If you are BnR reader please don't throw shit at a band or a concert. It rarely meets the intended target and takes out some random person you never intended to hit. It also pisses off the people around you, around the person hit, and the band. It is comical if you throw a bra or large panties on stage, but only if you are within the first few rows. This is all assuming the band doesn't suck. If it is My Chemical Romance throw everything you can.
 
At a Megadeth concert in Edmonton, Canada, some genius decided it would be a good idea to toss a liquid beverage toward the stage. However, this beverage hit the sound man and went all over the soundboard. It screwed up the sound for the entire show. A few fans remembered the experience like this:
 
"After some more time, they [Megadeth] finally hit the stage and after a few songs Dave addressed the crowd by saying he 'knows it sounds crappy,' but it was not there fault because the soundboard got fucked up. To be honest, it was so loud, I did not even notice the sound quality. After some more songs, he got on the mic again and said, 'Look guys, I already have two shoes on, so don't throw one up on stage.' Pretty funny banter, but then he went on, 'And if you throw any more shit up here, I will fuckin' walk off this stage and go right back to my dressing room.' Later, during 'A Tout Le Monde', two jackasses jumped the stage and ran over to him. They tried to put their arms around him and he shoved them away hard. Security finally got there and took them away. Now, to his credit, he did finish playing the song, but then without another word he took his guitar off and walked off stage."
 
Here is a video of Dave addressing the crowd at this show.
