A youth pastor thoroughly enjoyed movie night with his young charges, but towards the end of the evening, he got a popcorn hull caught in a back tooth. He worried at it with his tongue, tried snagging it with his fingernail, and even tried to brush it out when he got home, but nothing worked. Frustrated, he went to bed. In the morning, the gums around the popcorn hull were a bit swollen. His wife insisted he see the dentist, so he called. To his surprise the dentist told him to come right in. 

Once in the chair, the dentist had the offending hull out in a matter of seconds. "That's amazing!" said the pastor. 

"How did you do that? I tried everything I could think of but couldn't get it out!"
"Oh, Pastor," responded the dentist, "Don't you know that kind only comes out with prayer and flossing?"
