Some 23.49 million viewers tuned in to the "results" episode of Fox's American Idol Wednesday night that saw the judges use their once-a-season "save" for the first time. It rescued 23-year-old Matt Giraud, who received the fewest votes after his performance on Tuesday night. " Idol history has been made," Ryan Seacrest declared afterwards. But while other contestants crowded around Giraud, judge Simon Cowell remarked, "I wouldn't be so quick to congratulate him."
