Bradley Pitts (l), former bassooner, sits down with Zach Galifianakis. 

Zach's last episode featured an historic interview with Barack Obama, and it's surely just a coincidence that the president's popularity has been plummeting ever since. The only way for Between Two Ferns to follow that "get" is to do some mouth stuff with perhaps the world's biggest super star's husband, Brad Pitt. 

Watch for a surprise walk-on about halfway through.
