Eugene Levy, Catherine O'Hara, Daniel Levy and Annie Murphy -- playing their characters Johnny, Moira, David and Alexis -- all came together, via Zoom, to perform Carey's iconic tune "Hero" in honor of the teachers and students dealing with this difficult year.
To help with the tune, they were joined by many of their friends from the small town of Schitt's Creek -- including Twyla (Sarah Levy), Ronnie (Karen Robinson), David's husband Patrick (Noah Reid), Stevie (Emily Hampshire), Jocelyn (Jenn Robertson) and Ray (Rizwan Manji).
As the group crooned the tune -- led primarily by Patrick (considering that Reid is also a professional singer/musician as well as being an actor) -- they were all shocked when Carey herself crashed the Zoom chat to help sing the end of the tune.
"Moira, darling, I hope you didn't mind that I jumped in like that," Carey said, as David appeared to have a complete star-struck meltdown. "You all sounded so good that I had to get in on it."
"I think I'm having a heart attack!" David then yelled at the top of his lungs, before almost hyperventilating.
Carey then shared a heartfelt message to the students watching the Dear Class of 2020 special, and celebrated their impressive achievements, especially considering the monumental challenges facing them this year and in the future.
"To the students who had to deal with this bleak moment, congratulations on this historic accomplishment,” Carey said. "To all the students and teachers, you are so appreciated. And I just want to say, Class of 2020, you made it!"
To finish things off, Carey called out David specifically, before singing a few lines of "Always Be My Baby" as her adorable 9-year-old twins -- Moroccan and Monroe -- jumped up onto her lap. David simply passed out and fell to the floor.
The YouTube Originals special, Dear Class of 2020, was filmed over the course of the last several weeks. Its debut was shifted from Saturday to Sunday out of respect and deference to George Floyd's memorial service.
The commencement opened with Lizzo and the New York Philharmonic's performance of "Pomp and Circumstance," as well as remarks from Alicia Keys. Commencement speakers include Michelle Obama, Lady Gaga, Beyoncé, BTS, former Secretary of Defense Robert M. Gates, CEO of Google and Alphabet Sundar Pichai, and Malala Yousafzai, among many others.
