Christina Aguilera almost did a perfect job singing the national anthem at last night's Super Bowl. Repeating a line and flipping a word she sang "What so proudly we watched at the twilight's last gleaming" instead of "O'er the ramparts we watch were so gallantly streaming." Honestly if you weren't paying attention, if you were trying out the seven-layer bean dip or getting a fresh beer instead -- we won't tell -- you probably missed it.
