Vince Vaughn will participate in the Polar Plunge

This Sunday, hundreds of people will dive into the frigid waters of Lake Michigan as part of the Chicago Polar Plunge, an annual fundraiser for Special Olympics. Last year, Tonight Show host Jimmy Fallon participated in the event and this year the organizers have roped in actor and eternal manchild Vince Vaughn. The former Chicago resident and current owner of a $13.9 million penthouse in the Palmolive Building (it's for sale, if you've got the dough) was invited by Polar Plunge organizers, who asked Twitter users to reach out to the actor using the hashtag #VinnyDipping. Of course, Vaughn's participation isn't totally selfless—he has a new movie called Unfinished Business to promote. He'll undoubtably make a sophomoric quip about "shrinkage" after he exits the lake, before slipping on a hoodie and retreating to a hotel to continue working on the script for his Swingers sequel.
