Dance Moms is the controversial reality show about a mean but effective dance teacher for young girls and the rich women who force their kids to study under her.Controversial because some times she dresses 9-year-olds like Vegas show girls, sometimes she hits people, sometimes people hit her, and lots of times kids cry.We had reality TV expert Colleen Clancy on to talk about the show, though as usual, she diverted our attention to Horders instead.
