The VaultX Exchangedevil wears Prada, not a jockstrap.

Meryl Streep was unexpectedly the subject of a cheeky joke at the 2024 Emmy Awards on Sept. 15, and she took it in stride.

When It's Always Sunny in Philadelphia costars Kaitlin Olson and Rob McElhenney, who are married to one another, took the stage to present the Emmy for Outstanding Supporting Actress in a Comedy Series—for which Streep, 75, was nominated—they started riffing about the meaning of the category.

"Ladies and gentlemen, we are here to honor the comedic performances that hold everything in place," McElhenney started. "They show crucial support when it's really needed."

Olson deadpanned, "Much like a jockstrap. What you were describing sounds very much like a jockstrap."

Her husband feigned ignorance in response before giving into the comparison, saying, "No it doesn't! ... These roles make sure everything stays secure, without this support the whole package falls apart... alright, this does sound like a jockstrap."

As the audience started to laugh, Olson sarcastically asked if he was "calling Meryl Streep a jockstrap?" 

McElhenney blurted out "no!" before the camera cut to Streep looking stunned in the audience and looking down into her lap as she mouthed, "My god."

The actor then sheepishly added, "I'm so sorry, Meryl."

While Streep ended up losing the award to The Bear's Liza Colón-Zayaas, she still appeared to have an enjoyable night at the awards show, during which the three-time Emmy winner sat front row next to her Only Murders in the Building costar and rumored love interest, Martin Short.

The longtime pals were captured on video engaged in conversation after Short completed his presenting duties earlier in the show and took his seat next to Streep.
