A man is crawling along in the desert when he suddenly
sees another man approaching on a camel. When the rider gets
close enough, the crawling man says, "Please, can you help me?
I need some water."
"I'm sorry," says the man on the camel, "I don't have
any water. But I can sell you some neckties."
"Ties?" says the man. "I need water."
"I'll sell you one for four dollars."
"I need water," says the man.
"All right, two for seven dollars," says the man on the camel.
"Please!" says the man, "Can you tell me where the water is?"
"Okay, okay," says the other man, "You crawl down
about three more miles straight ahead. Just the way you're
going. After about three miles you're going to get to a stone.
When you get there, you're going to turn left. Crawl another
three miles and you'll get to the oasis. Are you sure you don't
want a tie, though? Three for ten bucks? That's the best I can do."
But the man just gets slowly up onto his feet and starts
staggering toward the water.
The man walks and walks and walks. Then he begins
crawling again until finally he gets to the stone. He brushes the
sand off it, and he sees an arrow pointing to the left. So,
turning left, he crawls on and on until he seems some palm
trees. He gets upon his feet and starts stumbling toward the oasis.
There is a man standing at the oasis, and the thirsty man
asks him, "Is this the oasis? Can I get water here?"
"Oh, sure, there's plenty of water here," says the other man.
"Oh, great," says the man as he starts to stagger toward
the water hole.
"I'm sorry," says the other man, "ties required."
