"I think a few years he's been doing it now. And this year he posted on Facebook and sort of dared people to do it too," neighbor Jolana Bernhardt told KARE.
Grotting said he got the idea from his brother and has carried it on through the years as a form of "lowbrow entertainment."
Another of Grotting's neighbors Diane Roman told the Star Tribune that his displays are one of the few things she looks forward to during the frigid winter months.
"It's the only funny thing about this weather," she said. "I always know the pants are going to be there."
This year, Grotting successfully inspired others in the area to share in his tradition as people posted photos of their own frozen jeans as well as full outfits and even bathing suits frozen solid on their lawns.
Grotting also promised to keep the tradition going as long as the weather remained cold enough to petrify the jeans or until, "my family gets too embarrassed."
