For all the pomp and excess of Madonna's Super Bowl halftime extravaganza, a single extended middle finger by guest singer M.I.A. is likely to be the most remembered piece of the show.
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" on CBS eight years ago. The brief exposure of Jackson's nipple during the 2004 halftime show raised a storm of controversy.
