Jimmy Fallon has taken a dip in icy Lake Michigan. "The Tonight Show" host took the plunge dressed in a suit and tie — then screamed and darted out of the water with a shocked expression on his face.

Fallon was making good on his promise to join Mayor Rahm Emanuel in Chicago's annual Polar Plunge if Emanuel would appear on his show.

Emanuel jumped in first, wearing shorts and a Chicago Public Library T-shirt.

Both were soaked from head to toe as they fled the water to cheers from a large crowd that had gathered on the Chicago lakefront to watch. A group of bagpipers provided the soundtrack for their rapid dash into the 32-degree water.

The event draws several thousand hearty plungers every year to raise money for Special Olympics Chicago
