I can beat that Sir Rabbit. When I was in North Dakota, we traveled across the border because the strippers got fully nude. I saw one sit on a MGD bottle and swallow it to the base.. I don't believe she gave the beer back, however...
The dirtiest, however, was in Columbus, GA, at the Traffic Light. After hours, the manasan would lock the doors and anything went after hours. I saw a lot go down after hours, but I guess the dirtiest was a gal was doing a bukakke show with about 6 GI's.
