Who's going to stop me?

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 suppose 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."
