Cerasus -
A woodcutter comes from the south, looking for work.
The forester says he's not interested but the woodcutter says give me a chance.
"OK" says the forester and hands the woodcutter an axe.
With a single stroke the woodcutter fells a small tree.
The forester says "impressive" - and asks him to try with a bigger, older tree.
Again he fells it with a single stroke.
The forester says "OK, here's a really big tree" - and sure enough the woodcutter fells it with a single stroke.
The forester says "OK you've got a job - but where on earth did you learn to cut trees like that?"
The woodcutter says "In the Sahara Forest".
The forester says "you mean the Sahara Desert?"
The woodcutter replies "Well it is now"
