A songwriting genius. His music is sort of folk-rockish and has nerdy lyrics involving zombies, nerd love and evil masterminds.

Floppy Haired Wide-Boy Jonathon R(W)oss, is a prominant Uk TV Prostitute who enthralls his misguided audience with a hilarious comedy speech defect routine that never fails to nauseate, Everything that comes out of his mouth is actually Shite. This is due to an Anus-Mouth swap operation he had at birth that proved so popular with the UK TV licence paying public that they voluntarily agreed to pay him 6 Million Pounds of their money, thus giving him the nickname 'The C**t!'.

Jonathon 'Dog-Cock' Woss's condition has improved in recent months after the successful removal of a slimy parasitic Russel Brand from his Rectum, the only side affect being his wife, Jordan's hair turing Pink!

A man easily worth his own page, Davis is the lead singer of the nu-metal band Korn (generally written as KoRn or with the Cyrillic character which appears to be a backward "R"). His lyrical quality is superb, though See You On the Otherside isn't his best work.
Jonathon Davis is fucking ownage! As I've previously stated, he needs his own page.
