Deluded and rude rapper Kanye West is no stranger to making a fool of himself, and his most famous blow-up came at the 2009 MTV Video Music Awards when Taylor Swift was awarded the coveted moon man instead of Beyoncé. Kanye took it upon himself to get up on stage as poor, unsuspecting Taylor was accepting her honor, and made the embarrassing rant of a lifetime.
