Sokrates: Why, the clouds of course. What's more, the proof is incontrovertible. For instance, have you ever yet seen rain when you didn't see a cloud? But if your hypothesis were correct, Zeus could drizzle from an empty sky. While the clouds were on vacation. Strepsiades: By Apollo, you're right. A pretty proof. And to think I always used to believe the rain was just Zeus pissing through a sieve. All right. Who makes it thunder? Brr. I get goosebumps just saying it. Sokrates: The clouds again. Of course a simple process of convection. Strepsiades: I admire you but I don't follow you. Sokrates: Listen. the clouds are a saturate water-solution tumescence in motion, of necessity, proces presentation when these distended masses collide- boom!
