When 'South Park' aired its anti-'Family Guy' episode, they received flowers from the crew of 'The Simpsons'
South Park fans may remember the episodes titled “Cartoon Wars” (parts one and two).
In the episode, it is announced that a Family Guy episode will air with the Muslim prophet Muhammad as a character.
Cartman apparently believes that the episode is offensive to Muslims and decides to go to Hollywood to try to get the episode pulled.
Jabs at Family Guy occur throughout the show. A few other big names in the cartoon comedy world loved it.
Trey Parker, co-creator of the series and the writer of the episode said “the day after that episode aired, we got flowers from The Simpsons. We got calls from King of the Hill, saying we were doing God's work. It's not just our opinion.”
Parker clarified what the show’s writers think of Family Guy in the DVD commentary:
"We totally understand that people love it, that's why we put it in the show, we understand that it speaks to some people and it can just be a simple laugh and that's great and we certainly don't think it should be taken off the air or anything like that, we just don't respect it in terms of writing."
He later referred to the writers behind the show as "smart" but emphatically criticized their overuse of "gag-humor".
