Famous stand-up comedian Norm Macdonald, a former “Saturday Night Live” writer and performer, tragically died Tuesday at just 61 after privately battling cancer for nine years, according to Brillstein Entertainment Partners, his management firm in Los Angeles.

Macdonald was an indefatigable stand-up comic and popular talk show guest whose death provoked an outpouring from fellow comedians.

“Norm was in a comedy genre of his own,” tweeted Sarah Silverman. “No one like him on this planet. Please do yourself a favor and watch his stuff.”

Macdonald, the son of two schoolteachers, was raised in Quebec City, Canada. He was a stand-up comic and briefly a writer for the sitcom “Roseanne” when he was picked to join the cast of “Saturday Night Live” ("SNL") in 1993.

He became known for his esoteric impressions, including Burt Reynolds, who gave Will Ferrell’s Alex Trebek character grief on “Celebrity Jeopardy.” He also impersonated Bob Dole, Larry King and David Letterman.

His deadpan style and skills as a writer made him the choice to host “Weekend Update.” O.J. Simpson was a favorite target. Macdonald opened the fake newscast the week of the former football star's acquittal on murder charges by saying, "Well, it's finally official. Murder is legal in the state of California."

Macdonald was fired in the middle of the season in 1998 by NBC Entertainment executive Don Ohlmeyer, a friend of Simpson's who reportedly didn't appreciate the "SNL" star-making Simpson the near-constant butt of jokes.

“I was never bitter,” Macdonald said in the oral history “Live From New York,” released in 2002. “I always understood that Ohlmeyer could fire me, because he was the guy who owned the cameras, so that didn't bother me. I was always happy that ‘SNL’ gave me a chance.”

He went on Letterman's show to announce that he was fired. During a commercial break, Letterman asked him, “This is like some Andy Kaufman thing with fake wrestling, right?" Macdonald recalled. But it wasn't.

Letterman was a fan who made Macdonald one of the guests in the CBS “Late Show” host's final run of shows.

In 2016, Letterman told The Washington Post, that the show would have had Macdonald on every week "if we could.''

“He is funny in a way that some people inhale and exhale, “ Letterman told The Post. "With others, you can tell the comedy, the humor is considered. With Norm, he exudes it ... There may be people as funny as Norm, but I don't know anybody who is funnier.”

The Post's story was headlined, “Will Somebody Please Give Norm Macdonald Another Show.”

As if to answer, Netflix two years later aired 10 episodes of an interview series, “Norm Macdonald Has a Show." Guests included Letterman, Lorne Michaels, Jane Fonda and Judge Judy Sheindlin.

He had limited success in other TV ventures. He created and starred in the ABC sitcom “The Norm Show,” later shortened to “Norm,” playing a former NHL player kicked out of the league for gambling and tax evasion and forced into community service as a social worker.

A Comedy Central show, “Sports Show with Norm Macdonald,” lasted only a handful of episodes, but he kept busy in comedy clubs.

“In my mind, I'm just a stand-up,” he told The New York Times in 2018. “But other people don't think that. They think, 'oh, the guy from ‘SNL’ is doing stand-up now,'”

Jim Carrey tweeted that Macdonald was “an honest and courageous comedy genius.” Seth Rogen said he essentially ripped off his delivery when he started acting.

“No one could make you break like Norm Macdonald,” Jon Stewart said on Twitter. “Hilarious and unique.”
