Amy Poehler is usually a good hang—but not during this moment. 

The Parks and Recreation alum recently reflected on a memory from a flight she took with her former SNL colleague Ana Gasteyer and Ana’s now 23-year-old daughter Frances amid filming for Mean Girls, and getting into a verbal altercation with a fellow passenger. 

“It’s a long story, but what happened was a first class guy—we were in first class too—he was like, ‘Excuse me, you’re being too loud in first class,’” Amy recalled during the Dec. 23 episode of Good Hang alongside Ana. “And my Boston came out, let’s just say that.”

For Ana—who shares Frances and Ulysses, 17, with husband Charlie McKittrick—it was “the best thing” she’d ever seen, adding, “The guy got mad you were swearing in front of the baby.”

Of course, Amy is far from the only star to stir the pot while filming a movie. Mark Ruffalo recently shared how he had to stop Now You See Me costar Woody Harrelson from a physical confrontation while shooting the 2013 film.
