I know it's a thinly-veiled promo for their upcoming movie, but I don't care. "The Hangover" is easily one of the funniest movies this year and I'm for anything that promotes it. While his previous interviews include Michael Cera, Jon Hamm, and Natalie Portman, Zach Galifianakis (who will become one of the most in-demand comedians in Hollywood after "The Hangover" hits) takes on his co-star Brad Lee Cooper in the latest installment of his popular FunnyOrDie web series, "Between Two Ferns with Zach Galifianakis".
Check out the video after the jump. "The Hangover" hits theatres on June 5th.
