I just had to add this to the last topic.
On the lighter side, here is a joke. A US Marine and a Iranian terrorist are fight in hand to hand combat and while they are fighting they both stumble across a Genie lamp. The terrorist takes it away from the Marine and they both agree to make one wish. The Iranian rubs the lamp and the genie comes out and offers the schmuck one wish. The Iranian says that he would like the genie to erect a wall around Iran that is ten thousand feet high and five thousand feet thick and could keep anyone from entering or leaving Iran. Within an instant the wall is there and the Iranian passes the lamp to the US Marine. The Marine scratches his head thinking about what he wants and then comes up with his wish. He asks the genie about the wall's dimensions and the genie confirms its size. He then askes if it is true that nothing or no one could escape when inside the confines of the wall and the genie again confrims that to be true. The Marine looks at the genie and says, "okay, then fill it with water!"
