Best WTF moment

If you had told me a year ago that the show-ending moment at this year's AMAs would be an incredibly entertaining performance by a South Korean pop star highlighted by a guest appearance by MC Hammer, I would not have believed you. I might have even said something inappropriate like 'you be tripping.' But both the South Korean pop star (Psy) and MC Hammer were on stage at LA's Nokia Theatre, performing the megahit 'Gangnam Style,' interpolated with Hammer's '2 Legit To Quit.' Definitely the most bizarre moment of the night.
