Bloodsucking sorority sisters and four other weekend wonders.

1. Vampires of any kind are bad enough. But something about sexy sorority chicks sporting fangs and the rolled up jeans and materialism of the 1980s is especially frightening. Assuming an undead girl never sucked on you, all your bad hook-ups will pale in comparison to the ice-cold hotties in Sorority House of the Dead, now playing on the Living Room stage at 1818 McGee.

2. See how sustainable you could be. Get ideas about eco-friendly home improvements, earth-loving products and more during the Green Scene Sustainability Show in Brookside at Border Star Montessori from 9 a.m. to 3:30 p.m. on Saturday.
