Tonight Show host Jimmy Fallon spent his Sunday morning diving into the freezing cold waters of Lake Michigan as a part of the city’s Polar Plunge.
I'm here Chicago! It is COLD. You are not making this easy. #PolarPlunge— jimmy fallon (@jimmyfallon) March 2, 2014
Fallon was joined by Chicago Mayor Rahm Emanuel.
Fallon agreed to make the plunge on his show Friday night.
The event raises money for Special Olympics.
Right now, it is 12 degrees in Chicago, so the water was much colder.
