On a cold Thursday in February, more than a hundred people dressed up in tutus, onesies and other ridiculous costumes and headed to downtown Minneapolis to do something even more ridiculous: jump into freezing cold water.
It was for a good cause, though. The Polar Plunge raises awareness and money for Special Olympics Minnesota.
Check out the video above for some Polar Plunge facts.
If you're up for the challenge, there are plenty more plunges where that came from. You can find one near you here.
