Between two ferns bloopers

Before his mainstream breakout role in 2009's "The Hangover," and before attracting fans spanning from frat boys to alt-comedy aficionados, Zach Galifianakis appeared on a low-budget, absurdist comedy show produced by a then start-up production company, Funny or Die.
Fast forward 13 years and "Between Two Ferns" boasts 22 episodes, its own full-length movie on Netflix, and big-name guests ranging from Barack Obama to Bradley Cooper to Justin Bieber. The show follows a semi-genuine, semi-fantasy format, with Galifianakis playing a fictional version of himself as he tosses insults and uncomfortable questions at his real-life guests. And oftentimes, the guests dish it back to Galifianakis, too.
