A Long Islander went viral this week for predicting the Knicks’ NBA Finals run in his 2020 high school yearbook.

Evan Pfeufer of Kings Park shared a photo Thursday of his quote in Smithtown High School West’s yearbook: “Knicks in 6. 2026 NBA Finals.” The post racked up more than 5 million views in just one day.

The now-23-year-old told The Post how he came up with the very specific prediction.

“It’s so simple. Knicks in six 2026 rhymes so incredibly well,” he said.

The Knicks superfan recalled his parents’ disappointment when he showed them the yearbook six years ago.

“It was so funny, my parents were like, ‘Evan, why? Why would you do this?’” he said.

Now, they are reconsidering and likening their son to a modern-day Nostradamus.

“My dad is questioning if I’m a human or not,” he said.

Pfeufer, whose impressive high school resume included serving as an officer in the Business Honor Society, purposely chose not to include any of his accomplishments on his yearbook page so that his Knicks quote would stand out.

“They gave us an option, and I said, ‘No, I just want this,’” he recalled.

“Hand on the Bible, I purposely didn’t put my honor societies and all the stuff I got because I was like, ‘What if this actually happens? Everybody else has this long-ass quote with all their achievements, and me, I would get it right.’”

As it started looking like his 2020 prediction could actually come true, he texted his childhood friend a photo of the yearbook page.

“And I was like, ‘Imagine if this happens,’” he said.

He then posted it on his private Snapchat and his friends encouraged him to share it on a larger platform. He submitted it to the sports Instagram account Overtime, which has 10.4 million followers, and it “instantly” went viral.

Pfeufer, who graduated from Adelphi University and now works as a sales rep, is hoping the post grabs the attention of the Knicks.

“My friend said, ‘If the Knicks don’t get you to one of the games or something, I would be livid,’” he said.

“I don’t expect anything, I’m just a guy with a prediction, but it would be pretty cool.”
