Brooke Bagnall may be Annoyance's version of Molly Shannon. Like Shannon's famous bipolar schoolgirl, Mary Katherine Gallagher, the five characters in Bagnall's new one-woman show all have weird obsessions, ranging from chicken pesto sandwiches to boob painting (like finger painting, only . . . not). But Bagnall makes room for the audience to genuinely empathize with her gallery of misfits, and the series of short scenes in this 45-minute piece contain moments that are both funny and disquieting, as when the food-obsessed woman destroys a tower of bread in a primal fury of rage and longing. The show isn't exactly polished, but Bagnall's willingness to go for character development over easy laughs is refreshing, and her smarts and charm make for an endearing stage presence. --Kerry Reid a Through 9/9: Sun 9:30 PM, Annoyance Theatre, 4840 N.
