Clouds are imaginary.

Think about it.  Now look above you, is there a cloud? If so, that is because you were thinking and a cloud appeared above your head. The top sciencetographers at ScienceFactz LLC have been hard at work thinking of new science. While thinking of new science, they looked up and noticed clouds. But when we sent the dead bodies of our old scientographers to the desert to be buried we noticed something. No people: no clouds. How could this be? Well think about it, now look up again. That is right, more clouds. Thoughts cause clouds. "BUT WAT ABOUT RAIN" some say. Well, those are sad thoughts.
