When in doubt you can always create a story, excuse or pure invention. This can be to decieve others or it could just be a clever marketing device.
When creating a story (i.e., making it up) it is important to do no harm. Inadvertently libelling, insulting or motivating an action not in someones best interest are to be avoided.
Of course marketing is intended to elicit positive action, sales, recognition, or support and it can be a bit subjective whether this is beneficial to others.
Humor
Keeping it light while sending a message (e.g., an obvious exaggeration or story) can often be an effective technique . In this way the exaggerated or often made up point can be useful in highlighting a hidden truth.
Satire is an example of this technique. The danger lies in the level of acceptance of the veracity of the story. If believed, when not intended as anything more than a philosophical message, harm could ensue.
Truth and Accuracy
Reputations are made and lost on the percieved level of trust granted them by others. Use of exaggeration and story telling can be an effective communication technique but overuse or misuse can erode the level of trust others have for you.
It is imperative a careful balance be exercised between the use of veracity and making it up. Each method has pros and cons and ca n be useful communication techniques but to avoid being misspercieved one must be cautious in how the technique is used.
