Above: More than 50 Super Bowl volunteers and their friends and family joined in a flash mob dance to Prince's "Let's Go Crazy" in St. Paul in front of the Rice Park ice palace. More than 50 Super Bowl volunteers and their friends and family surprised visitors to the ice palace in St. Paul's Rice Park on Saturday afternoon with a flash mob.

The group mingled inconspicuously by the towering 70-foot ice palace as ice skaters glided nearby and snow fell in the city park in a scene perfect for a Hollywood film. Suddenly, the park went silent as the DJ turned on Prince's "Let's Go Crazy." A group of women screamed with excitement and pulled out matching purple fur bomber hats and started dancing as the crowd parted. Other people of all ages joined in, sporting identical purple fur hats.

"I think we surprised some people," said Jenny Wood of Brooklyn Park, who works at Medtronic and decided to organize the flash mob. "It was fun."

She is one of the 10,000 people volunteering for the Super Bowl and still has one more shift left Sunday for the big game. While preparing to volunteer for the international event, she and other volunteers decided in November to plan a flash mob as a tribute to Prince and to show Super Bowl visitors how Minnesotans embrace winter and Minnesota Nice.

The group rehearsed for weeks at a Minneapolis dance studio with the help of a choreographer and threw in a couple cheers in the dance — "Let's go crazy" and the Skol chant. They're Minnesotans after all.
