For all the pomp and excess of Madonna's Super Bowl halftime show, it is likely to be a single extended middle finger by guest singer M.I.A. that is most remembered.The gesture, accompanied by a barely disguised expletive, came during a performance of Madonna's new single, "Give Me All Your Luvin."' At the end of her lines, M.I.A. appeared to sing "I don't give a (expletive)," although it was hard to hear clearly.The incident was reminiscent of Janet Jackson's infamous "wardrobe malfunction" eight years ago a surprise risque moment in front of tens of millions of unsuspecting viewers. The brief exposure of Jackson's nipple during the 2004 halftime show raised a storm of controversy and put CBS in hot water with the Federal Communications Commission.http://www.cbsnews.com/8301-207_162-...ea;fd.morenews
