Zach Galifianakis Spanks Justin Bieber Like A Baby

The Hangover’s Zach Galifianakis is changing the outlandish behavior of young Pop singers one adolescent at a time, and Justin Bieber is up next.

In Funny or Die’s “Between Two Ferns” installation, Galifianakis asked the “Beauty and a Beat” singer questions on his latest headlines, from peeing in a bucket at a restaurant to his Anne Frank comment. As the staged interview continues, Galifianakis becomes upset with Bieber’s “attitude,” and proceeds to removing his belt to lay down the law on the 19-year-old.
