Little Mary’s 1st grade class was on a field trip to their local police station.
There they saw pictures tacked to a big bulletin board label, "The 10 Most Wanted."
One of the youngsters pointed to the pictures and asked who those people are?
The policeman said; "They are very bad people and we want to arrest them."
So Little Mary said to the policeman, “Mister, why didn't you keep them when you took their pictures?"
