As he hits all the talk shows to promote his new movie, Birdman, Zach Galifianakis revealed what his own personal nickname for Barack Obama is. 

Of course, the two of them are best friends after Zach had his good mate Barack appear on Between Two Ferns, and he obviously has a special nickname for the President of the United States that no one else knows. 

Galifianakis was kind enough to let everyone know what that was on Jon Stewart last night, as he described his trip to the White House to film that particular special episode of the show, and we have to say it's not what we were expecting. It starts around the 3:30 mark, if you want to skip straight ahead to the action, but you should watch it all, it's darn funny.
