A duke was hunting in the forest with his rentinue if men-at-arms and
servants; he came across a tree.  Upon it, archery targets were painted
and smack in the middle of each was an arrow.  "Who is this incredibly
fine archer?" cried the duke.  "I must find him!"

After continuing through the forest for a few miles he came across a small
boy carrying a bow and arrow.  Eventually the boy admitted that it was he
who shot the arrows plumb in the center of all the targets.

"You didn't just walk up to the targets and hammer the arrows into the
middle, did you?" asked the duke worriedly.

"No my lord.  I shot them from a hundred paces.  I swear it by all that
I hold holy."

"That is truely astonishing," said the duke.  "I hereby admit you into my
service."  The boy thanked him profusely.  "But I must ask one favor in
return," the duke continued.  "You must tell me how you came to be such an
outstanding shot."

"Well," said the boy, "first I fire the arrow at the tree, and then I paint
the target around it."
