[Eddie Murphy imitating Bill Cosby's voice] "Yooouuu can not say filth flarn filth flarn filth in front of people." And I said, "I never said no 'filth flarn filth'!" He said, "You know what I'm talking about. I can't use the type of language that you use, but you know what I mean when I say 'filth flarn flarn flarn filth'." And I said, "I never said no 'filth flarn filth', and I don't know what you're talking about, and I'm offended that you called. Fuck you." And that's when Bill got pissed. "That's what I'm talking about! Yoooouuuu cannot say... 'fuck'!"
