"Integrity" heads up a list of the most-looked-up words of 2005. Not on the list: irony.

Ralph Whitehead, a journalism professor at the University of Massachusetts, said it might indicate the continuing discussion about American values and morality, or perhaps that integrity itself is becoming scarce so its definition is unfamiliar. "You hope integrity is a word everyone understands," he said.

You heard it here first,* folks: integrity has become so scarce that no one knows what it is anymore. Go Bob Ney!
