Whats the wierdest thing you've ever done to make a decision?

When I was younger, and I had two things to decide between, I would assign the two things in question a 1 or a 2. I would then close my eyes.

You know how after closing your eyes, you will still see traces of light? Well, what the traces look like vary from time to time, and I would determine if the traces of light more closely resembled a 2 or a 1, and that would be my decision.
