'Argo' Screenwriter Explains 'Argo F*ck Yourself' Line (NSFW VIDEO)

In the Oscar-nominated film "Argo," there is a line repeated throughout the story for comedic relief. Turns out, it provided a few laughs in real life, too.

On HuffPost Live Wednesday, "Argo" screenwriter Chris Terrio said the line -- "Argo F*ck Yourself" -- was actually a phrase used by real-life Hollywood makeup artist John Chambers as he worked on the phony film plan.

"It's a real joke that John Chambers, who's the character played by John Goodman, used to make when they were trying to relieve tension in the room," Terrio told HuffPost Live's Jacob Soboroff.

The screenwriter said including it in the film was one way to bring Chambers to life on screen.

"In the process of writing the film, you get these little gifts, these posthumous gifts from John Chambers, that his sense of humor finds its way into the film," Terrio said.

Chambers, who won an Oscar for his makeup work on "Planet of the Apes," died in 2001. He also worked on other CIA operations and was secretly awarded the agency's highest civilian award in the early 1980s.
