I feel like getting a Tigers hat, sunglasses, and a Hawaiian shirt ---- THE MAGNUM P. EYE BALL is the latest iteration of the Rude Mechs' fabulous annual fundraiser, this one erupting with Sellecky Hawaiian goodness, with live DJs spinning the island tunes, a silent auction of posh goods and services, mouthwatering treats by Leilah Stewart, potent potables for 200, and enough arts-friendly elbow-rubbing to cause chafing of the hipster gland. This night's popular event is how to enjoy yourself while supporting one of the best things about Austin. Sat., Aug. 18, 7pm-12mid. The Off Center, 2211-A Hidalgo, 476-7833. $40 ($70, couples; $15, starving artists). (Theatre Call Board) ----
