Comedian Jimmy Fallon took a quick but icy dip in Lake Michigan on Saturday – dressed in a full suit and tie – eyes bulging as he darted out of the slushy water and headed straight for a pile of dry towels.

“The Tonight Show” host 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 in New York, following an exchange of tweets and challenges.
