Aha that reminds me. Tre cool (drummer of green day) came prancing on stage and set off fire crackers in the middle of a bravery song. All of them jumped and stopped playing, and tre ran off. The lead singer than said (after they finished the song) that 'it is tre's main goal in life to scare the living shit out of me. Goodnight.' and then he stalked off stage with his band members hesitantly looking around and then kind of gave a bow and through their sticks and pics into the crowd and left.

Dude can't take a joke.... I feel sorry for the band members.
