A little boy was standing by his father watching him trying to put a floppy disk into his computer. The father was having trouble getting the disk to go in all of the way. The little boy said to his father, “Maybe it has a penny in it?”
Sure enough, when the father fished around inside where the disk was inserted, out came a penny. The father tried again, but the disk still would not go all the way in. The little boy said, “Maybe it has whole lot of pennies in it.”
