Funnyman Zach Galifianakis roasted U.S. President Barack Obama during the politician's appearance on his Internet comedy show. Obama joined The Hangover actor on his spoof chat show Between Two Ferns and was grilled on topics such as North Korea, his birth certificate and "being a nerd". During the humorous interview, which was released online on Tuesday (11Mar14), Obama was hit by questions including, "How does it feel to be the last black president?" and "Is it going to be hard in two years when you're no longer president and people stop letting you win at basketball?" Obama took the questions in his stride and even manage a few jibes back at Galifianakis, mocking the actor's film The Hangover 3, saying, "If I ran (for president) a third time, it would be like doing a third Hangover movie. It didn't really work out very well, did it?"
