Info: "Mankiw's 10 principles of economics, translated for the uninitiated", by Yoram Bauman, http://www.standupeconomist.com. Presented at the AAAS humor session, February 16, 2007. For the record, the talk contains two unattributed quotes ("9 out of 5" is adapted from a line attributed to Paul Samuelson - although apparently he said it about Wall Street indices, not macroeconomists - and "wrong about things" is paraphrased from P.J. O'Rourke's Eat the Rich) and, of course, the Einstein "simple" quote is an intentional misquote.
