Ben Bernanke, Alan Greenspan, and Jean-Claude Trichet are in the duck blind and a bird flies overhead.
Bernanke looks at it and says, "Looks like a duck, flies like a duck... it's probably a duck," shoots at it but misses and the bird flies away.
The next bird flies overhead, and Monsieur Trichet looks at it, then looks through the pages of a bird manual, and says, "Hmmmm...green wings, yellow bill, quacking sound...might be a duck." He raises his gun to shoot it, but the bird is long gone.
A third bird flies over. Greenspan raises his gun and shoots suddenly, brings it down, and turns and says, "Can someone go see if that was a duck?"
“Not everyone who calls out to me, ‘Lord, Lord,’ will be saved, but only the those who have done the will of my Father in heaven. Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name, drive out demons in your name, and perform many great deeds in your name?’ Then I will declare to them solemnly, ‘I never knew you. Depart from me, you servants of lawlessness.’”
Matthew 7:21-23
