Videos of a brawl between two groups of women at the Motor City Casino in Detroit have gotten thousands of views on the Internet. The casino is trying to reassure potential patrons that the punch-up early Friday in the Grand River Deli was not business as usual, The Detroit News reports. The casino said those involved in the brawl are under a permanent ban from returning. \"This is a highly unusual, very isolated incident,\" the casino said in a statement Tuesday. Videos taken with cell phones show women heaving shoes at each other and kicking and hitting as security guards try to restrain them. One video had gotten 20,000 hits by Tuesday and the other 12,000. The photographers apparently knew where their video would end up. On one video someone can be heard saying \"This is YouTube, in a heart beat.\"
