Little Johnny's kindergarten 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 criminals.

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 very badly to
capture him."

Little Johnny asked, "Why didn't you keep him when you took his
picture?"
