psychological quirk

Bush's 'I am about to lie' tag-line:

"Here's a debate-watching tip: Perk up your ears every time President Bush says 'of course' tonight.

Because if recent history is a guide, what's coming is a statement that his supporters might find obvious, but that his critics might consider a whopper....

Depending on where you're coming from, politically, [what he says is] either manifestly true or a Freudian slip exposing a significant falsehood....

Bush's views were being challenged that night, and his use of the phrase 'of course' sounded defensive in nature. So I decided to go back and look at how Bush used the phrase in other situations recently where he was confronted by tough questions...."

There is more, 'of course' (NOT a Freudian slip), and it makes for an interesting read.
