A general noticed one of
his soldiers behaving oddly. The soldier would pick up any piece of
paper he found, frown and say: “That's not it” and put it
down again. This went on for some time, until the general arranged
to have the soldier psychologically tested. The psychologist
concluded that the soldier was deranged, and wrote out his
discharge from the army.
The soldier picked it up,
smiled and said: “That's it.”
