I support the theory that headbanging causes brain damage. These are quotes from my latest study of a metal head who was forced to gradually headbang more and more often.
"That...guitar is proper....yeah man. Y'know?"
"Have you heard new Grab Death By the Bollocks? Proper good 'n shit because...guitars?"
"I bought the new Hate album with...uhm...m....m...mo...money?"
"I bought...Destroy...Box...shop...today...CD."
"Charlie fish trollop locked the sofa onto the weather earlier this morning yup yup I like floors."
"THEY'RE WATCHING! THEY'RE WATCHING! Hey man, how're...uhm...what was I saying?"
"Fuhmumble dorp bip bip bip"
"fuh fuh fuh water fuh? fuh gub gub"
The last time I saw him, he was going out every night and headbanging at 40 hbpm. Currently, all he does is drool in his wheelchair while staring into empty space, unless you play something like Maimed by Haters or Kill for Revenge, at which point he jumps up and continues to headbang.
