A man was crawling across the Desert dying of thirst, when a camel raced up and stopped. An Arab jumped down, opened a suitcase and said, "Would you like to buy a tie?"

"No,"said the man, 'I need water, do you have water?'
'No,' said the Arab,' but I do have a wonderful selection of ties.' He rode off, and the unfortunate man continued crawling across the hot sand until he came to a beautiful Hotel. He crawled up the step, crying: 'Water! Water!'
The Manager approached him and said, 'I'm sorry Sir, you can't come in here without a Tie!'
