There's apparently no stopping American Idol. Last night's third-season premiere attracted a deafening 28 million viewers, making it the night's most watched program by a landslide. It also helped boost the debut of My Big Fat Obnoxious Fianc&#233, which reeled in a big, fat 20 million viewers. Of course, if the second episode is as obnoxious as the first — and judging by last night's teaser, it will be — expect that number to tumble dramatically next Monday.
