I'm starting to think Derpy and Pinkie are related. Many of Pinkie's antics can only be explained as Pinkie being Pinkie. And the only way to explain some of Derpy's antics is that it's Derpy being Derpy.



And taken out of context, the phrase "Derpy being Derpy" can be taken in a bad direction. One miss of the Shift key and I'm screwed.
