A man on a camel rode through miles of sun-drenched desert searching for some sign of life. His supplies were running low when his camel died. Now, on foot, he desperately sought refuge from the heat and, most important, a source of water. Suddenly, he came across a vendor in the middle of the desert.

"Thank God I found you!" the man cried. "Please help me. I'm in dire need of some water."

"Well," said the vendor, "I don't have any water. But would you like to buy one of these fine ties?"

"What am I going to do with a tie?" the man asked.

"That's what I'm selling, sir. If you don't like it, I can't help you."

The man left the vendor and walked on for many more miles, praying each minute that he would find refuge from the scorching sun. His eyes squinted a bunch of times when he came across a restaurant in the distance. Unable to comprehend a restaurant located in the middle of the desert, he assumed the place was a mirage but decided to check it out anyway. As he approached the door, his mouth opened in amazement, seeing that the place actually existed.

The doorman stopped him before he entered. "Excuse me, sir," the doorman said, "but you can't come in here without a tie!"
