Recently, stars Scott Grimes and Dee Bradley Baker, along with executive producers Nic Wegener, Zack Rosenblatt and Parker Deay, celebrated the series at San Diego Comic-Con.
There, the team revealed the secrets to their long-running success.
"From a voice acting standpoint, I see very little of what's going into it. So, when I see an episode, I am surprised on all kinds of levels with the editing and the modification of lines since we originally read it, and so that's a lot of magic to me," said Baker.
Grimes echoed a similar sentiment, attributing the success of the show to "the behind-the-scenes people that just work their asses off."
"When we do a table read, we saw an episode today (last Saturday), that we did a table read for nine months ago, and I don't recognize anything, because it keeps going. Like, they do pickups, and it just gets funnier and funnier and funnier, so the product that we get to see at the end of the day has become so much better than what we started, and that's all these writers and creators," he said.
"The Simpsons," which is the longest-running animated TV series in the United States (with over 800 episodes), is motivating these writers to be more creative.
Wegener told us, "Honestly, a lot has to do with 'The Simpsons,' 'cause when you start talking about things, 'The Simpsons' already did everything. You're like, 'Okay, we can't do any of this, uh, so, I guess let's just make it super weird and see what happens.'"
But it's not just "The Simpsons" that are making the show better; it's the actors, too.
"Our main characters are amazing actors, so you give them weird stuff, and it's like, always better than you thought it was going to be," said Wegener. "Sometimes some bad stuff goes through because they make it seem good, and we don't find out until later down the line," he laughed.
"We have an amazing team of animators, directors that, like, you know, we write these insane scripts and they somehow- you look at the storyboards, and you're like, 'Oh, sh-. They were able to make that happen," Rosenblatt explained.
Wegener elaborates that the animators have "free rein" to add in what they think is funny and will enhance the story.
"They bail us out a lot. They bail us out a lot, actually," Deay joked.
