For the aspiring pop sensation, the opportunity to sing "The Star Spangled Banner" can easily turn into an exercise in one-upmanship. Who can have more superfluous trills, embellishments, and instances of unnecessary melisma? Well, future singers might have a tough time outdoing Kat DeLuna's 2008 rendition. If you can suffer through her lengthy, ahem, interpretation, the boos raining down from the Dallas Cowboy crowd are easily the best part.
