(An oldie but a goodie)

A preacher goes to a nursing home to meet an elderly parishioner. As he is
sitting there he notices this bowl of peanuts beside her bed and takes one.
As they talk, he can't help himself and eats one after another. By the time
they are through talking, the bowl is empty. He says, "Ma'am, I'm sorry, but
I seem to have eaten all of your peanuts."
"That's okay," she says. "They would have just sat there. Without my teeth,
all I can do is suck the chocolate off and put them back."
