During an uncomfortably funny interview with Justin Bieber on the Web show Between Two Ferns, Zach Galifianakis took spanking somewhere it’s never been. “It’s really exciting to talk to you, especially in the middle of your public meltdown,” the comedian shot at a smiling Bieber. “You've had three hairstyles. What’s next for your career?” he continued. The purposely offensive comments kept flowing until the Hangover star lost his cool, took off his belt, and gave Bieber three spankings. “You know what? I don't like your attitude, to be quite honest,” he said. “I don't think your mom would really mind if a stranger beat her son.” Of course, it was all fun and games.
