It was a Garden party … outside the Garden.
Thousands of frenzied Knicks fans took over Seventh Avenue Friday night to celebrate the team’s dominating win over the Boston Celtics in Game 6 of the Eastern Conference Semifinals at Madison Square Garden — with some climbing poles and one burning a rival jacket.
Knicks faithful roared as a sea of blue and orange poured out into the streets outside MSG exulting the shocking series upset that culminated with a blow-out victory over the defending champions.
Video showed shirtless fans climbing light poles on Joe Louis Avenue and 33rd Street, with others climbing on top of a taxi kiosk as hundreds of people gawked and recorded on their cellphones. Another showed off their callisthenic feats of strength on the 32nd Street sign to the delight of the crowd, video online showed.
Another Knicks fan lit a Celtics jacket on fire and held it up triumphantly.
However, the dense crowd on Seventh parted for a car carrying the most famous Knickerbocker fan, Brooklyn native Spike Lee — who stuck his head out of the sunroof and greeted the faithful with fist bumps and peace signs in papal fashion, according to video posted to X.
Fans were ready to turn their attention to the Eastern Conference Finals matchup against the archrival Indiana Pacers, who eliminated the Knicks in a seven-game series in the second round last year.
Beloved Knicks Jalen Brunson and Josh Hart are off-the-court friends with Tyrese Haliburton — the captain even facing off against his pal in the WWE ring last summer.
The first game in the series is on Wednesday back at the Mecca.
