(THEATER) Following last year's sold-out stints in Seattle and San Francisco, Circus Contraption's Grand American Traveling Dime Museum-a "veritable Confectionery of exquisite Novelties," as presented by a troupe of wry theatrical surrealists-returns for a fine-tuned, smoothed-out, and teched-up remount. Tonight's premiere is pay-what-you-can; all shows contain "mature content." (Magnuson Community Center Auditorium, Magnuson Park, Building 47, 7400 Sand Point Way NE, 800-838-3006, www.brownpapertickets.com. Fri-Sun through July 30; no shows June 24-26 or July 1-3. Doors at 7:30, shows at 8:00, $20.)
