TATTOO YOU: Got some killer body art you're just dying to show off? Head to the first-ever Chicago Tattoo Arts Convention, which kicks off tonight and continues through Sunday at the Hyatt Regency Chicago. Compare tats (maybe even enter one of the contests), meet tattoo artists from around the world, and check out a variety of vendor displays during this ode to body art. 2PM-midnight, $15, $35 for a weekend pass.
FAMILY TIES: Chicago's Lookingglass Theatre tackles the big questions of life in an intense adaptation of Dostoevsky's "The Brothers Karamozov." Already receiving rave reviews, the passion play continues through Dec. 7. 7:30PM, $30-$60.
HERO WORSHIP: Join Chicago Bears' legend Gary Fencik for Heroes Ball, a benefit for the Chicago chapter of Autism Speaks. The party takes place in the cool new Ravenswood Billboard Factory event space and includes an open bar, food, a silent auction and raffle, and entertainment by Ross Bon and the Mighty Blue Kings. 8:30PM, $80 (or come an hour earlier for a VIP reception for $125).
YOU'VE BEEN THUNDERSTRUCK: You've heard of them, now see them live. Thunder from Down Under, the cleverly named Australian male revue that has held court at Excalibur in Vegas since 2001, is coming to Crobar tonight. You know you're curious. 8PM, $20.
