To Halt Grinding, Schools Turn to... Burt Bacharach Kids warned to dance like grandma's watchin' By Jane Yager, Newser Staff Posted Feb 17, 2010 3:25 AM CST 7 comments Comments Keep those pelvises separate, or you won't like what you hear. (Shutter Stock) (Newser) – With some schools having kids sign no-grinding dance contracts and others threatening to turn up the lights and play Burt Bacharach, the crackdown on grinding at school dances is getting more creative. Schools and parents fed up with teens' overtly sexual dance moves are turning to unconventional methods to stop kids from grinding, wearing teeny-tiny skirts, and removing their shirts, MSNBC reports. One Minnesota principal started a "Dance Like Grandma's Watchin'" campaign with tongue-in-cheek videos about kids who are rejected by Harvard because of past grinding or sustain freak dancing injuries. Judging the campaign a success, the principal says that kids who don't mind shocking their parents feel differently about grandma. Tell that to teens at two Kansas high schools, who threw their own 400-student-strong homecoming bash after the superintendent banned their suggestive moves.
