Claire Danes came up with the catchphrase of the night when she saluted her Homeland co-star during her Emmy acceptance speech thusly: "Mandy Patinkin, holla."
Danes, taking the stage after winning best actress in a drama for the series, mentioned several names before matter-of-factly calling out Patinkin in the most unexpected way.
Twitter went nuts, with many people suggesting that this saying needs to become a meme, and soon.
As the pop-culture site Gawker put it: "'Mandy Patinkin, holla' is the new Angelina Jolie's leg." From New York Magazine's Vulture site: "'Mandy Patinkin, holla' is the best thank-you ever." And from National Public Radio's pop culture website nprmonkeysee: "If the internet doesn't remix 'Mandy Patinkin, holla' by tomorrow morning, it is a failure."
If someone can figure out a way to incorporate Patinkin's famous line from The Princess Bride - "Hello, my name is Inigo Montoya, you killed my father, prepare to die" - then the internet might truly be worthwhile after all.
Meanwhile, Danes loves that US President Barack Obama is a fan of Homeland.
"No pressure," the actress said backstage after her win.
"It's way cool that he is a fan. It speaks to the relevancy of the show and it's hugely validating."
Obama has said the series about a Marine returning home after being held as a POW, and who is now suspected by a CIA agent as working for al-Qaeda, is his favourite.
Danes' co-star and fellow Emmy winner, married actor Damian Lewis, joked to reporters that he might be doing some extra celebrating with her, despite the fact she came to the Emmys with a baby bump.
"We're going away to a romantic island together," the red-headed British actor joked.
"When that baby is ginger you guys are going to have a field day."
