Early to Bed, the grrl-positive erotic shop at 5232 N. Sheridan Rd., is holding a class tomorrow night at 7:30pm called "Flirting for Nerds 102." It's a more advanced version of the store's popular intro course, and promises to help even the most un-suave person make a pass. $10 at the door, 18 and over. More info on Early to Bed's calendar, or by calling 773-271-1219. By the way, they tell us there may be a film crew taping for a "documentary on nerd culture."
