Fat camp horrors, DIY surgeries, and a gender-bending Frankenstein—Chicago theatre does it all. There's still time to catch the local theatrosphere's most deliciously deviant productions (and a couple of shows stay open after Halloween is over).
 

A Nightmare on Lincoln Avenue V: "B" is for Blood

As if cutting carbs wasn’t horror enough, outdoorsy camp meets high camp as a group of nubile, weight-loss-obsessed teens start dying in spectacularly gruesome fashions (toxic waste, rampaging weather, serial-killing sociopaths) while trying to shed lbs at Dr. Atkins Kill the Carbs Camp.

8 p.m. Wednesday 10/30; Thursday 10/31. Cornservatory, 4210 N. Lincoln Ave. $7 Wednesday, $15 Thursday. (Cash only box office, BYOB). cornservatory.org.
 

All-Girl Frankenstein

Writer/director Bob Fischer, an off-Loop vet who consistently thinks outside the box, gives Mary Shelley's gothic adventure a gender makeover with a troupe of females taking on the iconic tale.

6:30 p.m. Wednesday 10/30; and 8 p.m. Fridays and Saturdays through 11/30. The Mammals at Zoo Studios, 4001 N. Ravenswood, Suite 205. $25. chicagomammals.com.
 

They Saved Hitler's Brain and Put it in Walt Disney

Leave the kids at home for this production penned by Billy Bermingham, the author of such infamous sex 'n splatterfests as Shannen Doherty Shoots a Porno and Cannibal Cheerleaders on Crack. Expect nothing less than Satanic sacrifices, DIY surgery, decapitation, and an on-stage orgy between Sarah Palin and a cadre of Big Oil titans.

9 p.m. Fridays and Saturdays through 12/7. $12. The Charnel House, W. Fullerton. thecharnelhousechicago.com.
 

Musical of the Living Dead

Taking inspiration from two Georges (Gershwin and Romero), the Cowardly Scarecrow Theatre rips into Marc Lewallen and Brad Younts musical narrative of apocalyptic tap dancing, blood-letting, and brain-eating. Bonus: If you sit in the front two rows, prepare to be liberally doused with flying scraps of flesh, brains, and blood.

8 and 11 p.m. Thursdays, Fridays and Saturdays through 11/9. $25. Cowardly Scarecrow Productions at Stage 773, 1225 W. Belmont. musicalofthelivingdead.com
