In case you've never heard of it, comedian Zach Galifianakis has a long running interview show called "Between Two Ferns" where he is literally between two ferns with A-list celebrities.
The questions that Zach asks often are inaccurate and make the guest uncomfortable. In this episode, Zach pulls off his belt and spanks the pop punk Justin Bieber.
It's nice to see that kid catch a spanking, even if it is fake. The series 'Between Two Ferns' might look familiar because there was a similar show on SNL with the late Chris Farley.
