"A man was in the desert, almost dying of thirst. Suddenly, he sees someone standing in the desert. He runs towards that person, and it's a tie salesman. Although the man begs him for water, the tie salesman only wants to sell him a tie.
'Why would I want to buy a tie in the middle of the desert?', said the thirsty man, who abandoned the salesman and continued to walk through the desert. It gets dark, and he sees something that looks like a mirage: it's a fancy restaurant, filled with elegant, rich people who are getting there by limousines and helicopters. He runs to the door, and begs on his knees to the doorman:
'Please, sir, a glass of water!'
'I'm sorry, but the dress code here demands wearing a tie.' "
I've read other 2 jokes written by him, but they were all not very funny, they were supposed to be tales with morale and stuff...
