Two prime ministers are sitting in a room discussing affairs of state. suddenly a man barges in, apoplectic with fury, shouting and stamping and banging his fist on the desk.

The resident prime minister admonishes him. " Crazy soul" he says "kindly remember the rule number 6."
whereupon Crazy soul is instantly restored to complete calm, apologizes, and withdraws.

The politicians return to their return to their conversation only to be interrupted yet again twenty minutes later by a hysterical woman gesticulating wildly, again the intruder is greeted with the word. "Evelyn, please remember rule number 6," complete calm descends once again and she withdraws with a bow and an apology. when the scene is repeated for the third time, the visiting prime minister addresses his colleague, "my dear friend, I've seen so many things in my life but never anything as remarkable as this, would you be willing to share with me the secret of rule number six?."
"very simple" replies the resident prime minister. "rule number 6 is, DON'T TAKE YOURSELF SO DAMN SERIOUSLY."
"Ahh," says the visiting prime minister, "that is a fine rule. " after a moment of pondering, he inquires, "and what may I ask are the other rules?"
THERE AREN'T ANY.
