Did you know that the current US $20 bill has a wrong eagle?

Eagles on currency and seals and that sort of thing are supposed to face to their right. This position (of looking to one's right, despite being seen from such a direction that they're looking to the viewer's left) is called looking 'Dexter,' which comes from the latin word meaning right. The alternative -- looking to one's left -- is called 'Sinister.' The large eagle watermark on the current US $20 bill is looking sinister, which is a national symbol faux pas by the treasury department, who could not be reached for comment.
