Bible

A father was approached by his small son who said, "I know the Bible!"

The father replied, "What do you mean you know the Bible?"

The son replied, "I know what the Bible stands for!"

The father said, "So what does the Bible stand for?"

The son replied, "It stands for B-asic I-nformation B-efore L-eaving E-arth."
