One of the best marksmen in the FBI was passing through
a small town. Everywhere he saw evidence of the most amazing
shooting. On trees, on walls and on fences there were
numerous bull's-eyes with the bullet hole dead centre.
The FBI man asked one of the townsfolk if he could meet
the person responsible for this wonderful marksmanship.
The man turned out to be the village idiot.

"This is the best marksmanship I have ever seen," said
the FBI man. "How in the world do you do it?"

"Nothing to it," said the idiot. "I shoot first and
draw the circles afterward."
