Peanuts?

A preacher visits an elderly woman from his congregation. As he sits on the couch he notices a small bowl of peanuts on the coffee table. "Mind if I have a few?" he asks. "No, not at all," the woman replies and pushes the bowl closer.

They chat for an hour and as the preacher stands to leave, he realizes instead of eating just a few peanuts, he has emptied the bowl. "I'm terribly sorry for eating all the peanuts, I just meant to have a few."

"That's all right," the woman replied. "Ever since I lost my teeth, all I can do is suck off the chocolate."
