Silly best marksmen joke

One of the best marksmen in the FBI was passing through a small town. Everywhere he saw evidences of the most amazing shooting. On trees, on walls, and on fences there were numerous bull's-eyes with the bullet hole in dead center. The FBI man asked one of the townsmen 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."
