It was twenty years later when I finally did. In January 2012 I was the keynote speaker at the Global Leadership Conference of GMAC, the Graduate Management Admission Council, a nonprofit organization of leading business schools which owns and administers the GMAT®. When explaining how hard it is to get reliable references, I referred to the funny little book I had so stupidly passed over. To my surprise, one of the participants raised his hand and shouted: “The author of that book is a good friend of mine, and I’ll make sure to get a copy to you!” Sure enough, a few weeks later I received in the mail a dedicated copy of The Lexicon of Intentionally Ambiguous Recommendations (L.I.A.R.) by Robert J. Thornton.
