A little boy was sitting on the curb eating from a sack of candy bars. An old minister came by and asked what he was doing. Boy says, "I'm eating my lunch."
Old Minister said, "You won't live to the age of 80 eating that stuff."
Boy says, "My Grandad lived to the age of 91."
Minister says, "Ill bet he didn't do it by eating junk food."
Boy says, "No, he did it by minding his own damned business."
