Bill Oakley, a former writer for the show, also tweeted that he was relieved that Trump never made an appearance on the animated series.

"I continue to thank God that Donald Trump was never invited to do a voice on The Simpsons even during the brief period when he was popular,” he tweeted on Sunday.

The panelists at the convention in San Diego also briefly referred to an episode in 2000 that joked about a Trump presidency, with Executive Producer Matt Selman saying the show doesn’t only make “terrible” predictions.

“The Simpsons” has poked fun of the Trump administration before, releasing a clip in April that parodied the president's first 100 days in office.
