As the crowd reportedly reacted with applause, Short said, "God bless." On Friday, news broke that the former Best in Show star died at the age of 71.

(O'Hara and Welch shared two sons, Matthew and Luke.) Shortly after news of O'Hara's death broke, many of her former costars on hit TV shows and films like Schitt's Creek and Home Alone shared poignant tributes to the actress via social media. "Ha-ha-HAAAA?!?! Her laugh was a perpetual 'Yes, And' challenged anyone who heard it to join in, and be as delighted as she was," Annie Murphy, who played O'Hara's daughter on Schitt's Creek, wrote via Instagram on Saturday, January 31. "Gosh, were we ever lucky to have her." Catherine O'Hara Shared What She Wanted to Be Remembered for Before Death She continued, "She would have never presumed to call herself a teacher (too self-deprecating, too Canadian) but holy f***, was I ever a student. Here a few Coles Notes for those who also want to study: Giggles always. Jokes first. As looking as they feel right in your bones. When you find the people you love and make you laugh, stick with your lovers and laughters. Everybody on set is a part of the community who (ideally) wants to make something great - treat them as such. Make suggestions, even if that means overstepping sometimes. Acknowledge if it doesn't work. Be appreciative to those who appreciate it when it does." O'Hara's onscreen husband and longtime collaborator Eugene Levy also mourned the loss of his dear friend. "Words seem inadequate to express the loss I feel today. I had the honor of knowing and working with the great Catherine O'Hara for over fifty years," Levy, 79, said in a statement to Us. "From our beginnings on the Second City stage, to SCTV, to the movies we did with Chris Guest, to our six glorious years on Schitt's Creek, I cherished our working relationship, but most of all our friendship." He continued, "And I will miss her. My heart goes out to Bo, Matthew, Luke, and the entire O'Hara family."
