Jimmy Fallon took a trip to Lake Michigan to partake in the infamous "Polar Plunge" but don't worry, he did it in style! Fallon made good on his promise to make Sunday morning's "Polar Plunge" with Mayor Rahm Emanuel as a condition for the Mayor appearing on Fallon's show, following an exchange of tweets. 

Emmanuel was clad in a green Chicago Public Library T-Shirt and shorts dived in first, followed by Fallon who was adorned in a suit and tie. The annual event draws several thousand hearty plungers to raise money for Special Olympics Chicago! Even though it's for a good cause it would take a lot to get me in those waters!
