Zach Galifianakis interviewed Conan O'Brien and Andy Richter on Between Two Ferns! AWESOME! Did you know Conan O'Brien was my favorite person when I was ten years old? Did you know Zach Galifianakis will be my favorite person when I am thirty years old? He's not my absolute favorite person now because as I reach adulthood, I'm gaining a new-found respect for my parents, making them my new favorite people. But I'll be done with them by thirty, and then it's Zach's turn.
