The Washington Post must hate to write this, but Billmon, DeLong and (I'm sure) plenty others had them nailed to the wall:

washingtonpost.com: Correction

On June 19 we wrote that wage increases had kept pace with inflation in the year to May, and criticized Sen. John F. Kerry for suggesting that wages had fallen behind. We were wrong and Mr. Kerry was right: Hourly wages for non-supervisory workers rose 2.2 percent, while the consumer price index rose 3.1 percent.

If they couldn't get it right the first time, at least they owned up to their lie (which incidentally undermines their whole sneering editorial)... this time.
