A Breif History of Opposite Day

Here we discuss the origins and consequences of what is know as Opposite Day.

Origins
It has come to the author's attention that one brilliant man, in what would be the most magnificent stroke of playground genius, created opposite day. "you are looking cool today" he said to his rival. "uh... hey, thanks!" was the reply. "Oh wait, it is Opposite Day!" quoth he. Then, his rival contemplated this masterwork of a conversation. He knew it was the ultimate in playground survival tactics. His use of the Opposite Day attack won him fame, wealth, and ladies, while the inventor, not quite aware of the brilliance he had unleashed, died in obscurity.

Paradox
The Opposite Day paradox is an important lesson that we can apply across the board. One can never express that it is currently Opposite Day. Any attempt to do so could be take as an opposite event, and thusly a circular logical loop arises. This must be planned in advance or retroactively. Additionally, and we wish to offer this for the gravest consideration of all, if you invoke Opposite Day, be prepared to stick with it for a day. All to often, Opposite Day lasts but a minute.
