What Did People Do Before The Internet?

Man, I just spent a good chunk of time trying to use my two hands and foot to represent the sun, moon and earth while trying to figure something out about lunar phases because the diagram I was looking at wasn't helping and I'm a horribly visual/active learner.

Then I remembered this was the internet and googled up an animation. Much, much more helpful.

But less funny, as I suspect I looked pretty damn ridiculous as I orbited my two fists around my foot and each other with a serious expression of concentration.
