A man is staggering through the desert, desperate for water. He comes across a little old man sitting at a table. On the table are lots of neck ties. "Please, do you have any water?" asks the man.
The little old man says "No, but why don;t you buy a tie? This one goes nicely with your shirt" "I don't want a tie, you idiot, I need water!" says the man. "Fine", says the little old man, "If you go over that sand dune and carry on for about a mile you will find a restaurant.
My brothers own it, they will have water. About two hours later the man staggers back. "Couldn't you find it?" asks the little old man?" "I found it" gasps the man.
