A man is crawling through the Sahara desert when he is approached by another
man riding on a camel. When the rider gets close enough, the crawling man
whispers through his sun-parched lips, "Water... please... can you give...
water..."
"I'm sorry," replies the man on the camel, "I don't have any water
with me. But I'd be delighted to sell you a necktie."
"Tie?" whispers the man. "I need *water*."
"They're only four dollars apiece."
"I need *water*."
"Okay, okay, say two for seven dollars."
"Please! I need *water*!", says the man.
"I don't have any water, all I have are ties," replies the salesman,
and he heads off into the distance.
The man, losing track of time, crawls for what seems like days.
Finally, nearly dead, sun-blind and with his skin peeling and blistering, he
sees a restaurant in the distance. Summoning the last of his strength he
staggers up to the door and confronts the head waiter.
"Water... can I get... water," the dying man manages to stammer.
"I'm sorry, sir, ties required."
