In the latest edition of his hilarious Funny or Die series Between Two Ferns, Zach Galifianakis speaks with Justin Bieber.
First, he references the singer's "public meltdown." Then, he insults his music.
From there, The Hangover star addresses Bieber's controversial stance that Anne Frank would have been a fan ("Did you mean that if the Nazis hadn't taken her, and she'd lived to be in her 80s, she would've liked your music, presumably due to loss of hearing?"), before delving into Justin's bucket peeing incident.
But Galifianakis didn't stop at mere verbal jabs and disses. He took off his belt and gave the artist a proper lashing. On his behind! For real!
