In a special appearance before United Nations inspectors whom he had invited to Iran, it's president, Mahmoud Ahmadinejad welcomed the men and women to Tehran personally.
"We will later this morning tour our nuclear facilities and I welcome you one and all", stated the leader. "But first, see this bright yellow ball? I will throw it in good faith and see if you can find it. It's an old custom here in Iran in welcoming guests. The first person to bring back the bright yellow ball, will have a wonderful gift later."
Mahmoud then pretended to throw the ball and hid it behind his back while the UN inspectors searched everywhere.
After an hour, Mahmoud called off the hunt and presented to one and all a treat as they were thirsty.
"Now before we go into the caverns, I must ask you to be ready. There are masks waiting. Just for fun, I've had these masks made to look like world leaders. Be sure and put them on because they can also protect you from a leakage."
Before entering the first cavern though, Ahmadinejad told the inspectors that the sign that you are in trouble should some leakage appear, is for the individual to roll over and play dead.
"Now let's all try it. You madam, you lead us in your interpretation so that the rest of us will know that you are in trouble and need to be helped out. Good! Now everyone on their backs with their feet into the air!" Good...Good!"
Later, the UN inspectors said they never did get into a cavern that contained nuclear facilities because of all the special training.
