In case you were wondering about the headline, the full quote is:
“There’s an old saying in Tennessee — I know it’s in Texas, probably in Tennessee — that says, fool me once, shame on, shame on you. Fool me, you can’t get fooled again.” —President George W. Bush, Nashville, Tenn., Sept. 17, 2002
The real saying is “Fool me once, shame on you. Fool me twice, shame on me”.
