Housewives' Most Desperate Hour

You can't blame Sanjaya for this one.

The supposed culprit behind "American Idol's" recent slide was nowhere to be found as "Desperate Housewives" sank to an all-time ratings low Sunday night.

The ABC soap drew 15.9 million viewers, big enough for its usual Top 10 finish in the latest Nielsen Media Research rankings, but small enough to raise questions, such as: What the hell happened to Wisteria Lane?

The show is quietly averaging 5 million fewer viewers this season than last, a decline of 22 percent.

Here's a look at last week's most watched shows:

1. "American Idol" (Tue), 26.7 million
2. "American Idol" (Wed), 26.1 million
3. "CSI," 21.7 million
4. "House," 20.4 million
5. Men's Basketball Championship, 19.6 million
6. "Dancing with Stars" (Mon), 18.2 million
7. "Desperate Housewives," 15.9 million
8. "Shark," 15.1 million
9. "Dancing with Stars" (Tue), 15 million
10. "Without a Trace," 14.1 million
