One day a preacher goes to visit an elderly lady. As he is sitting there talking with her, he notices a bowl of peanuts sitting on the table in front of him.

'Do you mind if I have a few peanuts?' he asks the lady.

'Help yourself,' she replies.

After about an hour and a half visit, he gets up to leave and notices that he has eated almost all of the peanuts in the bowl.

'I apologize,' he says to the elderly lady. 'I only meant to eat a few.'

'That's okay,' says the lady, 'Since I've lost my teeth, all I've been able to do is suck the chocolate off of them.'
