Wrapping up the 72nd Primetime Emmy Awards, host Jimmy Kimmel dropped a Zoom ID for viewers.
As the credits played, Kimmel invited guests to a virtual post-ceremony celebration, reading out the Zoom ID 4599567155.
It sparked a flurry of viewers who quickly recorded the numbers and tried frantically to log in.
With all Emmys afterparties cancelled due to coronavirus, some hoped the Zoom ID was an Easter egg that would get them into a virtual afterparty.
Some managed to crack the password needed to actually get into the call, although most who did so remained tight-lipped about it.
But a 100-person cap on the number of people who could enter the call at once meant even most who guessed the password missed out.
Meanwhile, for those who managed to crack the password and log in, here's what it looked like.
There didn't appear to be any Emmys stars on the call, or any indication the call was officially organised by the Television Academy.
So, what was the password to get in?
We don't know for sure.
A strange sign-off by Kimmel at the end of the ceremony may have been a clue.
"Stay safe. Please vote. And Baba Booey," Kimmel said before running around the empty studio room.
Some suspected "Baba-Booey" could have been the password.
Baba Booey is the nickname of US radio producer Gary Dell'Abate, who works on The Howard Stern Show. It eventually morphed into the show's catchphrase.
As for why Kimmel ended the Primetime Emmys broadcast with it, we may never know.
