Between Two Ferns with Zach Galifianakis is a comedy Web show starring, well Zach Galifianakis, strangely enough.

In it, he interviews celebrities in a passive-aggressive style, mocking them until they (usually) break. This week he interviewed Justin Bieber.

The celebrities are in on the joke, obviously, but it’s still funny to see them squirming as jokes are made at their expense. And lots are made at the expense of Bieber.

The interview comes to an abrupt halt when Galifianakis whips off his belt and gives Bieber a good hiding. Someone needed to do that, and it’s all the better for having been caught on camera.
