Ohmygod. I think i know. I saw one deaf metalhead at the bus stop. The 16 yr old or so chap was sportin a cool pair of earphones on his ears. When we got on the bus i sat down b4 he did n when he did he was infront of me n POOF! Like magic, the end of the earphone wire dangled down out of his pockets n he was still headbangin. Whoahohoho..that is the shit ppl! THE shit!
