Sen. Pat Roberts suffered the annoying problem of having his own phone go off during a Senate hearing today. But the reason it's making headlines is because of the amazing revelation that the 78-year-old's ringtone is the theme from Frozen. "Just let it go," he joked amid the laughter that ensued, notes Mashable. Roberts was questioning Agriculture Secretary Tom Vilsack at the time. A Roberts spokesperson tells the National Journal that the ringtone is for his grandkids and that he also uses Johnny Cash's "Walk the Line." (More Pat Roberts stories.)
