I have been exposed to a great amount of temptation throughout the course of my career.
I've had my run in with trouble. Fortunately, you know, one slap on the hand is usually the last time for me... I learned my lesson.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.
