If there ever was a flash mob worthy of your time, it’s the '80s-inspired "Thriller," and by now it’s a Halloween cultural institution in St. Petersburg. Can a bunch of zombies really be a “flash” mob? Nope, they’re sort of, well, obvious. And also, really well-rehearsed — so if you want in on the fun, join a rehearsal. On performance night (Oct. 24), all you zombies show your faces — your well-made-up-by-a-professional-makeup-artist faces. See you at rehearsal?
Museum of Fine Arts, 255 Beach Dr. NE, St. Petersburg. Every Thursday, with final rehearsal Oct. 18: 6 p.m. 727-896-2667, ext. 220.
