"Two men are walking in the woods. They come across a bear, which starts moving towards them to attack. The first man starts tying his shoes, getting ready to run. The second man asks him, "What are you doing? You can't outrun a bear." And the first man says, "I don't need to outrun the bear. I just need to outrun you."

The same is true of the GC. The GC doesn't have to be perfect, it just has to be better than you. And statistically, you suck at what the GC does.

Aka how to sail safely Without a Paddle. ;) Like the analogy and use of statistical argument.
