A kindergarten class went to the police station on a field trip. The police officer took the students past a wall with the Ten Most Wanted posters on display.

He expressed to the class that the police needed the help of the public to catch these fugitives. One student raised her hand and asked, “Are those the real pictures of the bad guys?”

“Yes, these are the bad guys,” confirmed the officer.

“Well,” pursued the kindergartener, “why didn’t you hold on to them when you took their picture?”
