Where: A warehouse in the South Side.
6:47 p.m. The Dirty Ball, Attack Theatre's biggest fundraiser of the year, kicks off the night with a Dirty Donor Reception pre-party. Seen enjoying special performances by Chatham Baroque were Christopher Hahn and Ron Booth, Clyde B. Jones, Larry Leahy and John Vandegrift, Catherine Loevner, Guinevere Glacier, Sean Gray, and Kate Colligan.
8:10 p.m. The VIP Velvet Lounge, designed by Richard Parsakian who stops to take a selfie with Rich and Cindy Engler, is actually a meat locker transformed into a futuristic red and silver spaceship. It's complete with shirtless robot mannequins standing guard while performers dance on the bars.
8:42 p.m. Mingle outside the lounge with roughly 1,000 guests enjoying interactive games, dance-offs and a confessional to share their dirty secrets. Who knows? You may run into an alien (Leigh Rock), Cleopatra (Sarah Damigh), or Emma McAfee channeling her inner punk-rock girl.
9:34 p.m. Everyone floods the stage to watch a special Attack Theatre pirate ship performance. The crowd, including Keri Harmicar and David Seman, giggles through a rendition of the '80s ZZ Top hit "Legs," in which pirates dance with a mermaid.
10:46 p.m. Co-chair Sam Badger flies by leaving a trail of glitter from the gold jacket he made just for the event. (If you need him, he's not hard to find!)
12:01 a.m. The party continues outside with an impromptu dance and drum circle. Patrons grab late-night treats from food trucks set up to indulge their cravings.
