On Sunday night, the Academy Awards ceremony was visited by someone who's even better at working a roomful of people: professional politician Vice President Joe Biden, who introduced Lady Gaga's incredibly moving performance of "Til It Happens To You." It was a departure from the normal Oscars routine, and even the (hilariously) political nature of Chris Rock's hosting stint. The Vice President gave an impassioned talk about the prevalence of sexual violence on college campuses (the subject of the Oscar-nominated documentary The Hunting Ground), and urged viewers to take a stand and to make a pledge at Arriving to the Indiana Jones theme, the Veep was greeted enthusiastically and had one of the lines of the night with "I'm the least qualified person in this room."
