Thousands of Univ. of Kansas fans swarmed a street near campus to celebrate the Jayhawks' NCAA championship Monday night -- with one fan actually surfing through the crowd in a shopping cart!!
The wild party all went down just moments after Kansas stormed back to win the title over UNC ... with roughly 70,000 people leaving their homes near Lawrence to cheer for the school's men's basketball team.
Video shows the scene was crazy -- people were shoulder to shoulder for what looked like a stretch of a couple hundred yards -- and at one point, a fan got in a cart and crowd surfed in it.
