Looking for Water in Life jokes

Arab was walking through the Sahara desert, desperate for water, when he saw something, far off in the distance. Hoping to find water, he walked towards the image, only to find a little old man sitting at a card table with a bunch of neckties laid out on it.

The Arab asked, "Please, I'm dying of thirst, can I have some water?"

The man replied "I don't have any water, but why don't you buy a tie? Here's one that goes nicely with your robes.

The Arab shouted, "I don't want a tie, you idiot, I need water!"

"OK, don't buy a tie. But to show you what a nice guy I am, I'll tell you that over that hill there, about 4 miles, is a nice restaurant. Walk that way, they'll give you all the water you want."

The Arab thanked him and walked away towards the hill and eventually disappeared from view.

Three hours later the Arab came crawling back to where the man was sitting behind his card table.

The man said, "I told you, about 4 miles over that hill. Couldn't you find it?"

The Arab rasped, "I found it alright. They wouldn't let me in without a tie."
