Blackhawks fans flooded the streets of Wrigleyville just moments after the final puck went in.
Things got a little rowdy as police had to move in.
A shirtless man was spotted on top of the Goose Island tavern sign on Clark Street.
He shouted at the crowd and they yelled for him to jump.
He didn’t do it, and instead slid back to the ground.
That man was among the crowd of a thousand people who packed Clark Street to celebrate the Stanley Cup victory.
Some fans took their celebrating a little too far.
At least one person was arrested in Wrigleyville.
Police say a group of people jumped onto a sculpture outside Wrigley Field, and one man was taken away in handcuffs.
People were also seen rocking a trolley on Clark Street.
Another man was spotted climbing a piece of construction equipment.
At least two injuries were reported from the overnight celebrations.
