Actually, I'm with Rainbow. If there's one notable thing I've learned about Equestria, it's that nature just doesn't work by itself (outside of the Everfree). Ponies have to make the leaves fall, they have to organize the snow, they even have to get the water back in the sky... it'd make perfect sense that rainclouds wouldn't rain without direct intervention. That pony's a rookie!
I'm too awesome to remember what's after 1...or after 3....or after that.... It's 2...between 1 and 3 it goes number 2....you use it in 20% cooler...sigh Hey BigMac! Don't use your fancy mathematics with ma friends! It's just counting up to ten! You don't even know that?!
