The New York Knicks clinched their first NBA title in over five decades over the weekend, turning a city known for its sharp elbows, grit, and tough love into a bastion of joy, painting smiles on fans and casual observers alike as cheers rang through the New York City streets and beyond.
Moments after the final buzzer sounded in San Antonio, Texas, where the Knicks beat the San Antonio Spurs in the fifth and final game of the NBA championship series, social media and news broadcasts were inundated with images and videos of fans across New York City taking to the streets to celebrate the team's performance.
"It is a beautiful thing," New York City Mayor Zohran Mamdani told ABC New York station WABC in an interview over the weekend. "The nation's largest city has become the world's smallest town, all of us thinking about the same thing."
He continued, "I was reading a piece this morning that wrote about how oftentimes in our city's history, this kind of unity comes in a moment of tragedy, and it's so beautiful that this unity is coming in a moment of joy."
Laurie Santos, professor of psychology at Yale University and host of "The Happiness Lab" podcast, told ABC News that science helps explain why people both in and outside of New York City are joyful about the Knicks' win.
"One thing we know about human psychology is that, you know, emotions are contagious," Santos said. "That's wonderful in a case where joy, excitement, you know, a sense of relief, all that stuff is contagious, and I think so many of us felt that with the Knicks."
She added, "I think a cool thing about this Knicks season is that even for non-Knicks fans, like the sense of joy and excitement for this underdog story has brought lots of people in."
Santos said "collective effervescence" occurs when groups experience joy and fun together.
"I'm from Boston. It is odd for me to feel swept up by the Knicks right now. I'm a little bit embarrassed by it. [But] it's very hard to watch these videos of people just screaming and cheering and not ... be affected by that," she said, citing the power of collective effervescence.
Actor Matthew McConaughey, a famed Texan, also noted the explosion of joy coming from New York City after the Knicks took the win in San Antonio over the weekend.
"America's more fun when New York's happy," McConaughey wrote in a post on X on Monday, congratulating the Knicks on their historic win.
Dan Harris, host of the "10% Happier" podcast and a former ABC News anchor, posted a video on social media Sunday speaking about his own impression of the collective behavior inspired by the Knicks' win.
"We're in a city where most of us spend most of our time focused on individual achievement, staring into our phones," said Harris. "But for the past few weeks, we've been pouring into bars together and living rooms and sharing an experience together."
Santos said sports fandom has "incredible benefits" when it comes to socializing -- benefits some on social media have opened up about in the wake of the Knicks' NBA Finals run.
Bryan Eng, actor and musician, highlighted the social benefits he witnessed in an Instagram post Saturday, ahead of Game 5.
"So, when the NBA Finals ends, are we gonna stop hanging out on Monday and Wednesday nights?" he asked. "'Cause I mean, I want the Knicks in five, obviously, but if I'm being honest, I ain't really been watching NBA until they got to the playoffs, and the real reason I've been doing it is 'cause I've been having a lot of fun hanging out with my friends at the bar."
"Seeing people, being more social -- my life has been so good with the Knicks," he added. "That's the greatest gift they've given me. Knicks in five, baby, but I still wanna hang out like there's a [Game] 6 and 7."
