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."
