Family Guy creator Seth MacFarlane has revealed the origins of one of the show’s most famous gags, which has since become a viral meme. The long-running animated sitcom, which began in 1999 and will start its 23rd season in February, has a history of controversial jokes and rarely holds back when choosing to mock certain celebrities.

Social media is inundated with Family Guy memes, and a particular one involving The Godfather resurfaces occasionally. Seth MacFarlane, creator and star of the long-running animated series, recently took to social media to explain the origins of the “it insists upon itself” meme that fans quote.

After a clip from a 2006 episode of Family Guy went viral, the show's creator and star Seth MacFarlane explained the origin of the famous joke in which Peter Griffin admits he didn't like The Godfather.

Even if you’ve never seen one of Family Guy‘s 400+ episodes, there’s a good chance you already know that Peter Griffin did not care for The Godfather. In fact, he’d go so far as to say that Francis Ford Coppola’s 1972 classic “insists upon itself.

Family Guy creator Seth MacFarlane shared some of the backstory on where Peter's classic "It insists upon itself" line came from.

Seth MacFarlane created one of TV's most famous families- the Griffins from Family Guy. Sure, he also created American Dad and the Family Guy spin-off, The Cleveland Show, but they didn't meet the success of his first masterpiece.
