Explaining social media to your parents is hard enough, but what if you had to explain it to Woody Allen? That was the situation Emma Stone faced when the 79-year-old filmmaker — and director of Stone’s new movie, The Irrational Man — asked her how Twitter worked.

In a recent interview with Conan O’Brien, Stone explained how Allen claimed he didn’t understand the point of the popular social media platform, “unless you are a musician advertising a gig or you are a comedian doing one liners.” Stone immediately set out to help, pulling up a tweet example from Joyce Carol Oates: “Tragedy plus time equals comedy.” Turns out Stone was caught off guard when Allen revealed that the line she read was actually one of the filmmaker’s own, taken from the 1989 film Crimes and Misdemeanors which he starred in alongside Alan Alda.

“My only example was his own quote,” Stone told Conan, before adding, “just another reason why he should probably be on Twitter.”
