"I have learned as a stand-up it's much better for acting to go the way of someone that has improv training and pay attention to that," says Galifianakis. "It is much better if it's a group effort. I always say less is more, for me. I don't need to say a lot of things. I don't want to say a lot of things. (in a whisper) I don't want to work."
The two have worked together a few other times, including a memorable video for Galifianakis' beloved Web series "Between Two Ferns" and a tour for Funny Or Die (the website Ferrell co-founded) in 2008 that played for college audiences of thousands. In Ferrell's opening, Galifianakis and other comics on the tour played ninjas attacking him.
"It was like a rock show," Galifianakis recalls. "It was like being in Toto."
"Or DeBarge," chimes Ferrell.
"DeBarge," Galifianakis solemnly nods in agreement.
