What can you expect?

What can you expect from a person who takes inspiration from a Monty Python Broadway musical? It's rather indicative of my mind set...a little off center, definitely warped sense of humor, curious about things no sane person cares about. For example, did you know the moon weighs 73,600,000,000,000,000,000,000 kg? My first thought is, ok, who weighed it? Since I'm guessing no one snuck a scale up on one of the moon landings, it's a estimate based on scientific formula. (a guesstimate, by any other name). Now, is that earth weight, or moon weight, because gravity is different on the moon, so things are lighter. (I see a future in spa ownership on the moon, where everyone's weigh-in would be a happy time!) So which is it? And did anyone ask the moon if she wanted her weight published for the universe to know? (I read it in a Snapple cap, and confirmed it on Wikipedia) Is this the same scientific formula they once used to prove the earth was flat? How well did that work, eh? One day a proven theory, next day a laughable myth. Isn't science fun?
