Chances are, if you are a celebrity, you have at some point been impersonated on Twitter. But in May 2009, Kanye responded to the authors of faux-Kanye Twitter feeds as only Kanye can. "I DON'T HAVE A F___ING TWITTER," he wrote in all caps ... on his blog. "HEY TWITTER, TAKE THE SO CALLED KANYE WEST TWITTER DOWN NOW ... WHY? ... BECAUSE MY CAPS LOCK KEY IS LOUD!!!!!!!!!" Can't argue with that logic.
