More than one hundred people took the plunge Saturday, and it was all for a good cause.
Leprechauns surfers, golfers and clowns all have something in common, it turns out.
That is raising money for the special olympics.
"The biggest thing is raise money for special olympics and also raise awareness for the special olympics program in nebraska," event organizer Jeff Boston said.
But it was not just showing up to Yanney Heritage Park in Kearney that earned them donations.
It was hopping in the frigid waters of the lake there.
"Once we get in, getting out is going to be the hard part," polar plunger Mike Connick said.
After the fact, others agreed.
Young plungers Brian and Alexa Mahalek described it "like an ice cube going through your body, kind of like you're wrapped around an ice cube."
Veteran and newbie plungers alike said they'll be back for more next year.
"It was just fun," polar plunger Daniel Eickmeier said.
There have been several of these fundraisers around the state in the last month or so to raise money for the special olympics.
Saturday's plunge in Kearney marked the last for this year.
