With manic grunts, crazed undulations, and an utter disregard for the personal space of others, the dancing wild man once again appeared without warning Tuesday at Calmar's popular nightspot the Horseshoe, leaving scores of patrons disturbed and disoriented. 'I was just standing there when 'Friends In Low Places' came on the jukebox, and bam, there he was,' said Jamie McAbee, describing her third encounter in five weeks with the mysterious gyrating figure. 'The next thing I know, he's waving his arms all over the place and knocking a beer out of my hand. It was horrible.' At press time, the dancing wild man was seen violently bobbing his head at Roscoe's Pub.
