GTL! Even though the novelty is starting to wear off somewhat, not everyone was able to hit Mike "The Situation" and Pauly D's first Chicago club appearance, so if you're itching to bust out that new Affliction t-shirt, hit Joe's Bar on Saturday and hang out with the "Jersey Shore" dynamic duo. Hairbanger's Ball will provide the tunes and the guidettes in the crowd will provide the entertainment. 9 p.m., 940 West Weed St., $20, $150 VIP
BABE WATCH: Don't pull a Borat when you check out Pamela Anderson at Woodfield Mall on Saturday. She'll be appearing at Sears to promote the launch of her new perfume. If that's not your speed, she'll be at Crobar later that night. Click here for details.
SABATOGE: It's too late to sign up for the Chidatarod, the annual race that combines elements of the Alaskan Iditarod and more than a few elements of shenanigans and tomfoolery, but we're guessing it's worth your time to come out and watch. The costumed race and pub crawl for charity kicks off at 12 p.m. Saturday at Wolcott Avenue and Hubbard Street.
TAKE THE PLUNGE: Hundreds will jump into the frigid waters of Lake Michigan Sunday for the annual Chicago Polar Plunge, which benefits Special Olympics. Registration is closed, but you can sign up at the beach, but a $100 minimum donation is necessary. Sunday @ 9:30 a.m., 1600 N. Lake Shore Drive
