Their Knicks mania couldn’t be topped!

Diehard fans climbed scaffolding, fire escapes, street signs — and even precarious treetops nearly two stories high — in desperate attempts to catch glimpses of their NBA champions parading down the Canyon of Heroes for the first time Thursday.

Wild video from Lower Manhattan showed revelers resorting to acrobatics almost fit for the basketball court to get a view of their hometown team’s first-ever ticker-tape parade, which an estimated 2 million people attended.

One maniac in a Knicks jersey dared to scale to the very top of a tree, where the branches seemed dangerously thin.

Elsewhere, a mass of fans decked out in orange and blue could be seen running around on top of scaffolding, hyping up the ecstatic mob below, video from the street shows. 

Others dared to hop up onto fire escapes for a better view, with video showing fans helping each other climb up.

In one chaotic scene, dozens of fanatics even packed on top of a pair of NYPD vans and a Department of Sanitation truck.

At least 20 revelers climbed on top of the South Ferry Station during the Knicks’ championship celebration — and ignored an MTA worker who pleaded with them to get down as they chanted “Knicks in five.”

Hundreds more could be seen climbing balconies, light posts and trees.

One fan wearing a Knicks jersey and a Batman mask was spotted watching the chaos from the solitude of a rooftop.

Luka Bouras, 15, of Westchester, climbed a tree where he stayed for hours — but instead of Jaylen Brunson and Karl Anthony-Towns, all he was able to make out from so far away was “some tall ass dudes.”

“It’s the first championship in 53 years. I’m not gonna lie, I cried a little bit when they won, and what better way to celebrate than climb a tree?” the teen said.

Cops told some fans to get off the scaffolding with a man standing on top of a garbage bin, downing a beer, but they were not about to blow up the celebration.

“What am I going to do?” an officer said. “He is not killing anybody.”

While most of the climbing chaos was in good fun, at least one led to an X-rated brawl between two women.

A wild video captured the moment the claws came atop the Trinity Place and Thames Street corner signs when one woman seemingly scolded another for twerking on the pedestrian signal — and tried to block her climb back down.

The dancing fan grabbed the jersey-wearing woman by the neck and ripped her off the street sign, but the tossed woman popped back up and ripped the lady’s pants down, revealing her Knicks-orange thong, and pounded her buttocks.

But the unbothered woman stayed on top of the street sign and began twerking as the crowd went wild.
