Robert Downey Jr. wasn’t the only one to make a surprise appearance at San Diego Comic-Con over the weekend. The Hollywood ties of presumptive Democratic presidential nominee Kamala Harris were deepened when she made an unexpected appearance at Saturday’s panel centered on The Simpsons.

Series creator Matt Groening teased the appearance of a “superfan” to the audience before showing video footage of the vice president quoting from the animated Fox show. In the clip, according to multiple outlets, Harris recites a line from the October 1996 episode “Treehouse of Horror VII,” in which Kang and Kodos impersonate then president Bill Clinton and Bob Dole at a 1996 presidential debate.

“Our country should move forward, not backward; upward, not forward; and always twirling, twirling, twirling toward freedom,” Harris says in the clip, originally filmed in 2013, as reported by the AV Club. The then California attorney general delivered the line as part of a University of Chicago scavenger hunt that saw students tasked with getting “an elected public official” to quote the line “either on video or in person.” At the end of the clip, which you can see below, Harris begins to laugh.

Harris’s surprise shout-out at the Comic-Con panel, which reportedly elicited cheers from the audience, comes on the heels of another connection to the show. Shortly after Joe Biden dropped out of the 2024 presidential race and eyes turned to Harris as the new nominee, some noticed similarities between the VP and one Lisa Simpson. The purple blazer and pearls that Harris wore to Biden’s inauguration created an outfit similar to the one donned by Lisa in 2000’s “Bart to the Future” episode, which features Lisa as “America’s first straight female president”—who inherits “quite a budget crunch” from former president Donald Trump.

Simpsons writer Al Jean then shared side-by-side photos of Harris and Lisa Simpson, writing on social media that this is a “‘prediction’ I’m proud to be a part of.”
