For years, male visitors to Vegas enjoyed production shows that featured hundreds of women so beautiful it was hard to imagine a place that could produce so many of them. Well, Sin City has evolved and there has never been a better time for female visitors to enjoy a well-developed half-naked male physique. A half-dozen well-produced male reviews have established themselves, but one stands apart from the others for their chiseled looks, mind-blowing bodies, dance routines, costumes and staging. Thunder From Down Under at the Excalibur Casino Hotel opened its Vegas engagement in July 2002. The revue has quickly become a "must-see" for any bachelorette party or group of women who think 10 sizzling hot Australian men taking their clothes off on stage makes for a fun evening. The troupe puts on their 90-minute show "World of Fantasy" twice nightly six days a week (dark Thursday) inside Merlin's Theater at the Excalibur, 3850 S. Las Vegas Blvd., 702.597.7600.
