Seth MacFarlane Talks 'Beef' With Jon Stewart Over 2008 Writer's Strike On Piers Morgan (VIDEO)

"It was an angry call," is how "Family Guy" creator Seth MacFarlane describes a little known conversation he had with Jon Stewart in 2008 on this week's episode of "Piers Morgan Tonight."

The "beef" as Morgan and MacFarlane describe it in the preview clip below, was instigated by a joke on "Family Guy" about "The Daily Show" returning to air before the Writer's Guild Of America strike back in 2007.

MacFarlane claims Stewart phoned him and said, among other things, "Who the hell made you the moral arbiter of Hollywood?"

MacFarlane, who seemed taken aback that Morgan even had heard of the incident, admits that he thinks Stewart "Was wrong not to shut his show down" during the strike which saw many beloved programs go dark, including "Family Guy." A few of the main issues argued during the strike included compensation for reality TV stars and TV content distributed online.

MacFarlane described the gag directed at Stewart as "Coming from the right place but probably so over the line," a much more measured response than Morgan was hoping for, who robustly asked MacFarlane to "Stand up for your jokes."

MacFarlane, while obviously not pleased with Stewart's call, did call the "Daily Show" host "An important voice in the sphere of rational thought."

In 2008, MacFarlane first detailed the phone call in a Q&A For Time, excerpted below:

"There was a very inside joke on "Family Guy" referring to the fact that he was working before the writers' strike was over. It was admittedly a very direct middle finger of a joke, which I don't discount. But he called and was very angry about it. The call lasted an hour. It was pretty amazing. He's a very good debater, I'll tell you that."

MacFarlane's full interview airs on "Piers Morgan Tonight" this Wednesday, Oct. 5 at 9:00 p.m. EST.
