George was lost and wandering in a desert, when he stumbled upon an oasis... The oasis was a Jewish man who was selling ties. The man holds up a rack of colourful ties and says, ""Hello, sir. May I interest you in purchasing a tie? They are normally ten dollars, but for you, sir, I will only charge five."" Having been wandering for days without a drop of water George promptly replies, ""No, I have no use for a tie, but please, sir, do you have any water? I have been wandering for days without a drop to drink."" ""I'm afraid I don't have any water to share with you"", replies the Jewish man. ""But if you continue walking a few hours East, you will find another oasis. At that oasis there is a restaurant. You will be able to get some water there."" George heeds the mans advice and begins walking East, only to return to the oasis of the Jewish man many hours later. ""What's the matter?"" Asked the Jewish man. ""Did you not find the restaurant?"" George relied, ""They wouldn't let me in. I didn't have a tie.""
