Justin Bieber was whipped by Zach Galifianakis during his interview on Between Two Ferns.

Galifianakis interviewed Bieber on his show, which was posted on Funny or Die on Sept. 26. A slightly cocky and bored-looking Bieber seemed prepared for the surly funnyman's jabs. Galifianakis played on Bieber's boyish image asking him if he got a toy with his happy meal. Bieber smoothly deflected the question by throwing it back at Galifianakis. He even had his moments of conquering -- when Galifianakis asked him if he knew what Galifianakis was doing when he was Bieber's age, the 19-year-old pop star suggested that he was probably finishing the fourth grade.

A miffed Galifianakis asked Bieber to keep his punk attitude in check. Galifianakis also defined Bieber's career by his various hairstyles, saying, "You've had three hairstyles, what's next for your career?"

But the highlight of this interview came right after Galifianakis brought the incident of Bieber's peeing in a bucket being caught on tape, and set-off on a righteous rant, "You're too young to be smoking pot and pee-peeing in buckets and driving up on the highway fast. I don't think your mom would really mind if a stranger whipped her son!" At this point Galifianakis had his belt in his hand and he whipped away. 

Recently, Bieber also made a video mocking the reality TV show, Intervention, which he posted on Instagram on Sept. 25.

In the Instagram video, Bieber parodied the reality TV show, Intervention. In the clip Bieber fake cries as he says, "Because I know somewhere deep down in my heart I still love you," to which a friend of Bieber's wails comically.

The bit is culled from an Intervention scene from a pretty old episode of the show, which dealt with addiction:
