A little boy forgot his lines in a Sunday School presentation.
His mother, sitting in the front row to prompt him, gestured and formed the words silently with her lips, but it didn't help. Her son's memory was blank.
Finally she leaned forward and whispered the cue, "I am the light of the world."
The child beamed and with great feeling and a loud, clear voice said, "My mother is the light of the world."
