Sahara Forest:

A little withered old man walks
into a timber company office, and applies for a job as a lumberjack. The
foreman politely tries to talk him out of the idea. After all, he is old,
small, and apparently much too weak to fell trees. The old man picks up an axe
and walks over to a huge redwood. As he goes to work, a high-pitched whine
comes from the axe, chips of wood fly everywhere and the odour of burning wood
fills the air. In record time, the old man is finished chopping down the
tree.
"That's just
astounding," the foreman, says, "wherever did you learn to chop down
trees like that?"
"Well now," the old
man smiles "have you ever heard of the Sahara Forest?"
"You mean the Sahara
Desert. "
"Sure, that's what it's
called NOW. . . "
