Six-year-old Angie and her four-year-old brother Joel were sitting together in church. Joel giggled, sang, and talked out loud. Finally, his big sister had had enough. 
"You're not supposed to talk out loud in church." 

"Why? Who's going to stop me?" Joel asked. 

Angie pointed to the back of the church and said, "See those two men standing by the door? They're 'hushers'."
