“Handmaid’s Tale” star Elisabeth Moss left Jimmy Kimmel in genuine shock earlier this week.

The Emmy winner dropped by “Jimmy Kimmel Live” on Tuesday to promote “Handmaid’s” upcoming final season, but when asked about any mementos she might keep after wrapping the Hulu series for good, Moss shared one particular story that sent Kimmel into tailspin.

“We had an email sent to all of the [executive producers] that was a full list of all the props and costumes that we could take,” Moss said Tuesday. “And in a very mature way, I wrote back ‘dibs’ — and then proceeded to say everything I wanted.”

The actor said she naturally requested to keep her character’s underwear, which had been specifically designed to fit her, only for somebody in the company-wide email exchange to inform everyone that “someone already asked for it.”

“Wait a minute,” said Kimmel, processing her story. “This is your custom underwear that you wore, and some creep on the staff requested it? In writing, requested it? Like, ‘I want Elisabeth’s underpants, I’m gonna take ‘em home, I’m gonna put ‘em in storage for a while.’”

Moss laughingly agreed when Kimmel called his storage hypothesis the “best-case scenario,” but went on to explain that she doesn’t “want to know” who claimed her undergarments, as she still wants “to work with these people.”

“What kind of a crazy thing is that to say?!” Kimmel exclaimed. “Oh my God, I hope it’s a woman. I mean, really. Someone made a formal request for your underwear, like, in writing, in an email, that they shared with other people. We need to know who that person is.”

Moss appeared unbothered, however, and joked that she’d “find out” before coming back.

“The Handmaid’s Tale” was adapted from Margaret Atwood’s 1985 novel of the same name and is set in a dystopian future where the U.S. government has been overthrown by a patriarchal theocracy — which forces Handmaids, or remaining fertile women, into slavery.

The final season premieres April 8 on Hulu.
