This ferocious three-woman sketch troupe blows through pretensions with sharp scenes culled from its previous shows. Rebecca Fox, Laura Grey, and Heather Simms skewer mundane jobs, casual racism, exclusive organizations with arbitrary rules, and sex- and violence-oriented television journalism. As directed by Gary Ashwal, Tara DeFrancisco, Joe Janes, and Megan Kellie, these sketches are wildly creative and laugh-out-loud funny. In one, a graphic artist tells her roommate that she’s a gerbil because she’s so embarrassed at spending her days designing macaroni and cheese boxes; in another, the three become creepy goth-rocker “equal-opportunity ghosts” who insist that prejudice is silly because all souls taste the same. In contrast to its earlier shows, Triplette uses no video and few masks here. But their almost propless performance only serves to show how tight they’ve gotten. Though there’s a different opening act each week, this troupe doesn’t really need a warm-up. Through 7/30: Sat 10:30 PM. Apollo Theater studio, 2540 N. Lincoln, 773-935-6100. $7-$10.
