(ABC News)-- March Madness celebrations went into overdrive after upset wins at both the Final Four games on Saturday.
Fans of the University of Kentucky Wildcats celebrated their team's win over the University of Wisconsin-Madison by pouring into the streets, cheering and engaging in their traditional celebration ritual -- lighting couches on fire.
The game came down to a nail-biter last second three-point shot, but riot police in Lexington, Ky., had gathered before the game ended along heavily trafficked streets to keep order. Many students ended up taking selfies with officers as they celebrated their team's win, according to the Lexington Herald-Leader newspaper.
Scattered arrests were reported in the area and several objects, including couches and T-shirts, were set on fire by fans.
The practice of lighting couches on fire after a big basketball game is so common in Lexington, that the local newspaper published a PSA before the game reading: "Only you can prevent couch fires!"
One fan didn't appear to take that to heart and was filmed dancing while spinning some flaming object.
In Lexington police were not able to give out the exact number of those arrested -- or of how many couches were set ablaze -- as of Sunday morning. According to the Lexington Herald-Leader, one person was shot in the arm Saturday night after the game, but it was unclear whether that was related to the celebrations.
In Storrs, Conn., thousands of University of Connecticut fans watched the Huskies upset the top-seeded University of Florida Gators. After their team won, fans flooded the school's Gampel Pavilion and streamed out into the streets.
According to The Associated Press there were 20 arrests made in Storrs, but most fans celebrated responsibly.
"The vast majority of our students have been both respectful and responsible," Storrs Chief of Police Barbara O'Connor told the AP.
