LMAO! Justin Bieber’s antics has taken someone over the top! Justin stopped by Funny or Die’s “Between Two Ferns” with Zach Galifianakis (The Hangover) – nuff said! They talk about Justin “pee-peeing in buckets” and “time-traveling” back to Anne Frank’s days. “I don’t like your attitude to be…honest,” Zach says, and proceeds to take his belt off and bring it down…Justin’s back-side. Hit the jump and check out the oh-so-funny material.
