My undergraduate experience was at the U.S. Coast Guard Academy. The cadet honor code was "A cadet neither lies, cheats, steals, nor attempts to deceive." You can say something that is technically not a lie but choose your wording in a way that is tries to deceive. That is just as bad as a lie in my book.

The winner of most dishonorable is a virtual tie between Hillary and Barack. Click here to see a table that lists all of the lies, deceits, and exaggerations.
