A preacher visits an elderly woman from his congregation.  As he sits on the couch he notices a large bowl of peanuts on the coffee table.

"Mind if I have a few" he asks.

"No, not at all" the woman replied.

They chat for an hour and as the preacher stands to leave, he realizes that instead of eating just a few peanuts, he emptied most of the bowl.

"I'm terribly sorry for eating all your peanuts, I really just meant to eat a few."

"Oh that's all right" the elderly woman says. 

"Ever since I lost my teeth all I can do is suck the chocolate off them."
