There are things a Princess cannot do. Over the centuries, Celestia has been asked to do those things countless times. And the moments when her ponies need her the most are the ones where she can't do anything.
Rainbow just discovered water balloons. Discovering why ponies don't use them is going to take slightly longer.
Shortly after the Elements were rediscovered, somepony decided the new Bearers needed combat training...

Discord teaches Fluttershy a lesson on the frequent nature of public debate. (Any resemblance to the Internet is purely dejecting.)
