Chicago Improv Festival Through Sunday at various locations; $5-$18 The week-long tribute to all things spontaneous closes with a flurry of weekend shows. We like all-female troupe Boner Petit (10:30 p.m. Friday at Playground Theater) whose show is as raunchy as their name implies, and Bearded Men Improv (9 p.m. Saturday at Athenaeum Theatre). They're from Minnesota, so you know it's gonna be funny. More: Check out our top picks for Improv Fest.

The Meat Locker
8 p.m. Friday-Saturday at Zoo Studio; $10; call (866) 593-4614 for tickets

Production company The Mammals put on this disturbing show about Meat (Dave Goss), a journeyman boxer whose life is in danger if he ever gets knocked out. Unfortunately, he ends up on the wrong end of a fixed fight arranged by Benny the Bookie (Roy Gonzales). Needless to say, this is no Rocky ending.

>Gold Coast Film Fest
6:30 p.m. Saturday at Royal George Theatre Center, 1641 N. Halsted St.; $40
The sixth annual event has developed a cult status as an underground short film festival featuring the best of Chicago amateur cinema. While the budgets might not be high, the quality is sure to impress. Get there early for the pre-party and stay late for the (in)famous post-show party. Your ticket includes admission to the festival and two drinks at the pre-party, located next door at Landmark Grill.

B.B. King 8 p.m. Saturday and Sunday at House of Blues; $76; get tickets Yeah, it's a steep price tag, but you're paying to see a living legend. And since the king of blues is now 82 years young, there may not be many more chances to catch him live. Love-song crooner Rachel Cantu opens.
