Today on This Week in YouTube, Leah D'Emilio & Lon Harris help you sort through the hottest videos on the tube - from Obama's inauguration to Joaquin Phoenix rapping. Also, we send "Mansone" some feedback after her "comeback" last week. You make the next call, BUTtPOP! Remember - we're mocking YouTube so you don't have to. Congratulations to this week's Mahalo prize pack winners! Subscribe today and you could win, too!
