Update: The video is here, and it's a hilarious support video for Hillary Clinton (except for Karen, who is obviously a Donald Trump supporter). The video went live during the first presidential debate between Clinton and Trump. Check out the cast in their signature roles in the video above. The original story is below.

The Will & Grace cast reunited, but the reason for the happy get-together is more mysterious than the current season of American Horror Story and Lost combined.

On Sunday (September 25), Eric McCormack, Debra Messing, Sean Hayes and Megan Mullally shared a heap-load of photos of the cast palling around, 10 years after their hit NBC comedy ended. But this isn't your average cast reunion where the stars get together to swap stories, catch up and indulge in nostalgia. The photos appear to show the gang back to work on the Will & Grace set!

"I remember this place," Mullally captioned a photo that seems to show her standing at the entrance of apartment 9C, where Will and Grace lived throughout the show's eight-season run.

I remember this place.

In another pic, McCormack is holding a script entitled "Hot Food," joking about how he used to be able to read his lines without glasses. The same title also appears on all four actors' social media accounts, along with corresponding character names straight out of I Love Lucy: Ricky (McCormack), Lucy (Messing), Fred (Hayes) and Ethel (Mullally).

The actual reunion happened on Wednesday, according to a tweet by McCormack, but whatever the secret project is that the cast is working on is expected to be revealed very soon.

"I feel like something BIG is going to happen tomorrow," Messing wrote on Sunday evening.

On Monday, Hayes shared a photo of the cast in costume and a trailer on his Facebook page that featured the words "Will & Grace is back" in bold red letters, while Mullaly is heard off-screen chanting Trump's name and exclaiming, "Make America bueno again!"

Is the show really making a comeback? What's with the I Love Lucy references? Where's Rosario? Is this all just an elaborate campaign ad for Hillary Clinton?

It looks like we'll just have to wait and find out.
