Acknowledgement: In addition to the references provided at the end of several posts, I would like to acknowledge that I also regularly consult with the most interesting man in the world, especially in connection with complex scientific matters. (YouTube link below, if you
must know the identity of this incredibly modest and low-key person.)
http://www.youtube.com/watch?v=PVwG1t-NVAANo need to refer to him as The Most Interesting Man in the World (i.e., capitalized), because, as he notes: "There is only one most interesting man in the world."
