Hey, genius — we're talking to you. If you can quit working on all those formulas in your head for hypercube surface movements and differential calculus equations for, like, two hours or so, why not drag your enormous prefrontal lobe to Room 175 of the Regnier Center at Johnson County Community College (12345 College Boulevard in Overland Park, 913-469-8500) for today's "Think Fast!" annual Mensa Testing Day? You and your giant throbbing brain will need to bring along $40 and a photo ID. Register by 12:30 p.m. for a 1 p.m. test. If you're between the ages of 14 and 17, you'll need parental permission; younger children, frankly, are not yet smart enough. Then just score in the top 2 percent.
