Little Johnny's kindergarden class was on a field trip to their local police station where they saw pictures， tacked to a bulletin board， of the 10 most wanted men.
One of the youngsters pointed to a picture and asked if it really was the photo of a wanted person.
“Yes，” said the policeman. “The detectives want him very badly.”
So Little Johnny asked， “Why didn't you keep him when you took his picture？”
