Disclaimer: this will make you literally laugh out loud.

On the latest installment of his hilarious Funny or Die interview series, 'Between Two Ferns,' Zach Galifianakis gives Justin Bieber a long overdue spanking. The bearded funny man lectures the teen pop star about how he's "too young to be smoking pot and pee-peeing in buckets" before laying the belt on dude. Happy meals, haircuts and his legion of loyal "Beaners"; the banter sprinkled throughout is brilliant, too.
