The mere mention of his name usually makes people's skin crawl (or, alternatively, provokes ridicule), so I present to you, in honour of his birthday, a list of things for which he is responsible:
Butterfly tattoos
Crazy Town
Being one half of the worst rumoured couple in history - seriously, can you even imagine him with Britney Spears?
Fighting Scott Stapp, which turned into the most hilarious feud ever.
Far too many white kids wearing pants sagged so low it looks like they soiled themselves
Emo, which seems like a reaction against nu-metal but is really just the same thing, but minus the down-tuned riffs and Adidas clothes and with black eyeliner tacked on
