Norm Macdonald’s been dubbed a comedic genius for his subversive brand of comedy, but penning his forthcoming memoir reminded him that he’s had “no education.”

“The scariest [part about writing a book] is I have no education and so I really feel like to be a good writer, you need education,” the comedian, who never graduated high school, told Page Six on Thursday after hosting “Gotham Comedy Live.” “My son has [an] education. He’s a much better writer than I am, and he’s only 20.”

Starting from when Macdonald was born in Quebec City, Canada, and spanning his storied career — writing for “Roseanne,” appearing on “The Drew Carey Show,” becoming a household name as an anchor on “Weekend Update” on “Saturday Night Live” to ultimately being fired in 1998 from the Lorne Michaels-created show — the 52-year-old certainly has plenty of material to work with.

“I’ve never worked so hard. It was very hard for me to keep a whole book in my head. I could keep a sketch in my head or even a movie … but a book. It’s so hard to keep that whole thing at once in your head,” he explained.

“If you like a good old-fashioned tell-all bombshell about sex, drugs, and rock ’n’ roll, and if you like an unflinching account of how the dirty little business of big-time comedy works, then you will love ‘Based On A True Story,’” Macdonald wrote in the publisher’s announcement last December.

“OK, one time I do flinch. But only once. The rest of the time, unflinching. Also, there will be no mention of rock ’n’ roll. I was lying.”

The 250-page, 100,000-word book was “supposed to take a year” to pen, but it “took five years,” Macdonald revealed. “I’d read it and then as soon as I read it, rewrite it. Read it, rewrite it. Read it, rewrite it.”

But for someone who struggled with telling his own story, Macdonald’s found solace in the work of the greats.

“I just read the Russians. I don’t read anything modern. I haven’t read anything modern ever in my life. People try to turn me on to stuff and I go, ‘Well, I don’t know,’” he said. “If it’s happy, you call it classic. They call it classic if it’s around for a couple hundred years, so I’ve gotta catch up. It’s going to take me my whole life.”

“Right now I’m reading ‘Don Quixote.’ I’m reading [another] book called ‘In Search of the Lost Time.’ Those are the two books I’m reading on the road. I have lots of time. I’m on the road too much,” he continued.

While Macdonald crawled his way through his memoir’s completion, his son, Dylan, is studying writing at the University of Iowa.

“He just likes writing. I love that he has a passion,” Macdonald said. “My dad was a very good storyteller, so I wrote down a lot of his stories, but I threw them all out. It came from an oral tradition. My son got published incredibly fast.”

“[Dylan] has work ethic and a passion for it … I get frustrated and feel like I’m losing my mind when I’m writing, but he’s the opposite. He’s young. He has incredible talent that I don’t. He has education. He knows how to craft. Without craft, you can’t make art.”

The “Dirty Work” actor, who reasons that he “did all right” for someone who never earned a diploma, added that his son’s academic career has made him realize he has “big holes” in his education, but he’s not opposed to getting back in the classroom to fill in the gaps.

“I would really like to go to school. I never got the chance,” he said.
