Even with below freezing temperatures outside, Jimmy Fallon took on frozen Lake Michigan to raise money for The Special Olympics.

“Absolutely not. I’ll donate money. I’ll do whatever else. I’m not — I mean, that was just crazy,” the comedian, Jimmy Fallon said of Sunday’s Polar Plunge.

Jimmy Fallon with Mayer Rahm Emanual took the Polar Plunge in North Avenue Beach, last Sunday to raise money for The Special Olympics. He came out in a suit and tie and encouraged everyone else to wear a tie as a sign of solidarity.

#SwimmyFallon #PolarPlunge trended all over Twitter and even celebrities came out, like Gold Medalist — Nick Goepper.

The Plunge raised over $900,000 for The Special Olympics.
