Our five-year-old son went to a church conference with my wife and me. 

He got restless, so my wife handed him a pad and pencil and suggested he mark down every time the speaker said the word "and." 

After a while, he grew bored, and I asked, "Would you like to listen for a different word?"

"Yes," he whispered.  "I'd like to listen for 'Amen'."
