In this story:
The New York Knicks' celebration of their historic NBA Cup championship took an unexpectedly hilarious turn when Josh Hart decided to go completely out of pocket during the trophy presentation. The moment became viral gold, showcasing the tight bond between Hart and superstar teammate Jalen Brunson in the most outrageous way possible.
During the Knicks' dominant 124-113 victory over the San Antonio Spurs at the T-Mobile Arena in Las Vegas, Hart couldn't resist pulling off a prank that would immediately go viral.
While the team celebrated on stage, Hart poked his thumb directly into Brunson's backside while the guard held the championship trophy. Brunson's reaction was priceless, he quickly jerked away and shot Hart an angry stare before realizing what had just happened. The moment was caught on camera in crystal-clear 4K, and Hart knew he couldn't deny it.
Rather than issue a serious response or apologize, Hart took to X and embraced the chaos with humor. He posted "Damn in 4k…..😂😂😂😂."
