The United Kingdom's favorite dirty old lady Miriam Margolyes is infamous for her free-wheeling fart humor, which has been immortalized on TikTok and become a part of British television history.

So you might assume she'd get a kick out of Arnold Schwarzenegger farting in her face while the two were working on a film in the 1990s. But you would be full of hot air.

Margolyes, best known on these shores for playing Professor Sprout in the Harry Potter franchise, recently told the story on the podcast I’ve Got News For You. To say the incident raised a stink would be putting it--well literally, but also mildly.

What a monster.

The incident between Margolyes and the former Republican Governor of California occurred on the set of the 1999 horror film End of Days, and suffice to say, Margolyes is not at all fond of "the Governator."

Acknowledging her status as Britain's foremost master of flatulence, Margolyes told the podcast hosts:

“He was actually quite rude. He farted in my face."

"Now, I fart, of course, I do – but I don’t fart in people’s faces. He did it deliberately, right in my face."

Margolyes went on to describe how it all went down.

"I was playing Satan's sister and he was killing me, so he had me in a position where I couldn't escape and lying on the floor."

"And he just farted. It wasn't on film, it was in one of the pauses, but I haven't forgiven him for it."

So were Margolyes and Schwarzenegger on better terms before he broke both wind and their friendship? Not so much.

Margolyes, who has become so liberal in her politics as she's gotten older that she recently joked she "had difficulty not wanting [British Prime Minister] Boris Johnson to die" when he had COVID-19, said of Schwarzenegger:

“He’s a bit too full of himself and I don’t care for him at all. He’s a Republican, which I don’t like.”

On Twitter, the story of course had people cutting up.

Even Schwarzenegger's son was like "excuse me, what now?"

Let this be a lesson to us all to just leave the farting to Margolyes from now on.
