Science or something.

You know how earlier today, you were saying to yourself, "This is a pretty decent day, as far as Saturdays go, I guess. But do you know what would really pitch this Saturday over the edge? A bunch of balls dropped onto an escalator for non-specific reasons!"

I always assumed that science was more about observing bacteria through microscopes, and less about annoying people who just want to get the hell upstairs.
