From Dictionary.com <http://dictionary.reference.com/search?q=cynic> [Latin cynicus, Cynic philosopher, from Greek kunikos, from kun, kun-, dog. See kwon- in Indo-European Roots.] Word History: A cynic may be pardoned for thinking that this is a dog's lif e. The Greek word kunikos, from which cynic comes, was originally an adjective meaning “doglike,” from kun, “dog.” The word was probably applied t o the Cynic philosophers because of the nickname kun given to Diogenes of Sinope, the prototypical Cynic. He is reported to have been seen barking in public, urinating on the leg of a table, and masturbating on the street. Quoting Michael Carnes <michaelcarnes@earthlink.net>:

You? A cynic? Guy, that's hard to believe...
