Operator is a game played by children. It goes like this:
Everyone sits in a circle.
One person starts by whispering a phrase into their neighbor's ear.
That person then whispers the same phrase into their neighbor's ear.
This continues until the message gets back to the starter.

By then, the message has been distorted, usually to the point that it makes no sense, whereas it was at least a complete sentence to begin with.

The point.
Operator illustrates the disintegration of facts and events when they are disseminated through oral tradition.

Which is a reason I don't believe anything written in the Bible as being historically correct. All (ok, "all" is mighty inclusive, but we can assume most) the stories of the Bible were passed through generations as oral traditon before they were written down. And even then, they were transcribed to appease whoever was in power.
