His longtime friend Bob Saget, whom Macdonald famously roasted on Comedy Central in 2008, wrote, "Devastated. Met Norm in Ottawa when he was in my audience at 17 years old. Been close for decades. We have lost a comedic genius. No other voice in comedy has been as uniquely prolific, brazen, dark, hilarious, and heartfelt. Love you forever, Norm."

A representative for Saget also told EW the actor and comedian would be releasing a special episode of his podcast Bob Saget's Here For You on Thursday, titled "Remembering Norm."

SNL also honored Macdonald, issuing a statement that said, "Today is a sad day. All of us here at SNL mourn the loss of Norm Macdonald, one of the most impactful comedic voices of his or any other generation. There are so many things that we'll miss about Norm -- from his unflinching integrity to his generosity to his consistent ability to surprise. But most of all he was just plain funny. No one was funny like Norm."

Steve Martin, another SNL alum, tweeted, "We loved Norm MacDonald. One of a kind."

David Letterman praised Macdonald's talent in a statement provided to EW. "In every important way, in the world of stand-up, Norm was the best," he said. "An opinion shared by me and all peers. Always up to something, never certain, until his matter-of-fact delivery leveled you. I was always delighted by his bizarre mind and earnest gaze. (I'm trying to avoid using the phrase, 'twinkle in his eyes'). He was a lifetime Cy Young winner in comedy. Gone, but impossible to forget."

Jim Carrey tweeted, "My dear friend Norm MacDonald passed after a brave 10 year battle. He was one of our most precious gems. An honest and courageous comedy genius. I love him."

Former Daily Show host Jon Stewart praised Macdonald's talent for making even the most seasoned pros burst into laughter. "No one could make you break like Norm Macdonald," he tweeted. "Hilarious and unique."
