Mariah Carey made the cameo of all cameos!

On Sunday, during YouTube’s Dear Class of 2020 broadcast, the cast of Schitt’s Creek reprised their roles to congratulate graduates.

In the sketch, Dan Levy, Annie Murphy, Eugene Levy, and Catherine O’Hara address viewers, thanking teachers and commending students during a Zoom video call.

Then, they were joined by Mariah who sang “Hero.”

“Moira [Catherine’s character], darling, I hope you didn’t mind that I jumped in like that,” the singer said. “You all sounded so good that I had to get in on it.”

“I think I’m having a heart attack!” shouted Dan, whose fandom for Mariah is a long-running joke on the show.

“To all the teachers and professors — especially the ones who had to deal with students like me who never really showed up to school on time — you rose to the occasion and helped these students reach the finish line,” Mariah said

“And to the students who had to deal with this bleak moment,” she continued, “congratulations on this historic accomplishments.”

We love this!
