Stephen Hawking used to drop in on Simpsons table reads

“One year, or a couple of years, he was just hanging out—he would come to table reads and be there hanging out,” Selman told The A.V. Club during a phone interview previewing the show’s upcoming episode, “Homer Is Where The Art Isn’t.” “Like, ‘There’s Matt Groening. There’s Dan Castellaneta. There’s… Stephen Hawking. At the read. Just enjoying our world.

“I think he saw that there’s a certain absurdity in everything, like in trying to figure out the laws of the universe or silly Simpsons stories. I think he shared that absurdist sense of humor. Our show is sort of about trying to find meaning in a chaotic world—I think he related to that as well.”

Speaking with The Hollywood Reporter, Simpsons showrunner Al Jean echoed Selman’s observations about that sense of humor, noting that the groundbreaking theoretical physician and bestselling author gave his blessing to the joke in “They Saved Lisa’s Brain” in which Homer mistakes Hawking for Hustler publisher Larry Flynt. Hawking’s one request of the show, according to Jean: “He did say at one point that he did not want to be drunk on screen.”
