Anthony Clark’s former “Yes, Dear” co-star Mike O’Malley described their final phone call while announcing the actor’s death via X.

“We spoke on the phone three weeks ago,” the 60-year-old tweeted Wednesday, alongside throwback photos.

Clark had O’Malley and his wife, Lisa, “laughing loudly” during the conversation.

Clark and O’Malley played Gregory “Greg” Warner and Jimmy Hughes, respectively, on “Yes, Dear,” which ran on CBS between 2000 and 2006.

O’Malley “was a fan before [he] was a friend,” he wrote Wednesday.

“He was a hilarious guy,” O’Malley told his followers. “When my wife, Lisa, and I were dating back in the mid-nineties, Anthony was already famous in Boston, regularly selling out comedy shows.”

He continued, “The first time we saw him at The Comedy Connection we laughed and laughed and laughed. He was so unique — one of those comics who is laughing along with you at the absurdity of his stories and observations.”

Since O’Malley revealed Clark’s passing on social media, other comedians have paid tribute to the “Boston Common” alum.

“Reno 911” star posted a throwback photo with his “best friend” via Instagram, writing, “He was a massive stand-up out of Boston and I opened for him for years.”

He added, “I had so many great times with this dude. Nonstop laughs. I hope he is at peace now. RIP Tony.”

O’Malley commented, “Anthony loved you Nick. He was always bragging about your comedy from the get-go.”

While Clark’s official cause of death is not yet known, Deadline reported that he died of complications relating to pneumonia.

It is unclear whether Clark is survived by a partner or children as he kept his personal life out of the spotlight.

The comedian, additionally, has not acted steadily since 2006 when “Yes, Dear” wrapped and he hosted a season of “Last Comic Standing.”

His most recent roles were in “My Uncle Rafael” in 2012 and “West of Liberty” in 2019.
