Let’s Watch Tina Fey React to Jimmy Kimmel’s Bill Cosby Bit at Emmys 2016 Again, Shall We? GIF

Just like Us, the star-studded crowd at the 2016 Emmy Awards was visibly shocked when the show's announcer invited Bill Cosby to the stage on Sunday, September 18. All smiles inside Los Angeles' Microsoft Theater quickly fell flat — including Tina Fey's.

As the camera cut to the six-time Emmy winner, 46, she turned to pal Amy Poehler and appeared to whisper, "Oh, this has got to be a joke," while fidgeting with one of her earrings. Unbreakable Kimmy Schmidt star Ellie Kemper also looked dismayed as her big smile quickly turned to a serious grimace.

Luckily for Fey and Kemper, it was just a joke. Host Jimmy Kimmel subsequently took the stage and reassured the audience that the 79-year-old Cosby Show star — who has been accused of sexual assault by more than 50 women — was not at the ceremony.

"Don't worry, he's not really here," the Jimmy Kimmel Live! host, 48, said. "I just wanted to see what you guys would do."

Some viewers took to social media after the not-so-funny practical joke aired to point out that Fey and Poehler previously joked about Cosby at the 2015 Golden Globe Awards.

"I don't know if you saw this on the news today, but Bill Cosby has finally spoken out about the allegations against him," the Mean Girls writer said during her opening monologue at the time. "Cosby admitted to a reporter, 'I put the pills in people, the people didn't want the pills in them!'"

"No, Tina, that's not right," Poehler, 45, replied at the January 2015 ceremony. "It's more like, 'I got the pills in the bathroom and I put them in the people!'"

Cosby, who is set to stand trial next year in a sexual assault case, has denied the allegations.
