The title is incorrect, but the writer refuses to make a correction as it looks better this way. But he wishes to make it very clear that it is Doctor Derpicus, not Doctor Derp. Within Goldie's cottage lies the most evil of creatures... Doctor Derpicus. Evil schemes, from a tiny- ...body. An unexpected source for Equestria's greatest evil genius. Only one pony can stop him, but does she stand a chance against such brilliance? He thinks not. Not this time.

Author Note:
Uh. Yeah, so this is a thing that kinda exploded outta my head. I'm not sure if it's "comedy" but it is quite silly. But "silly" is not a category, so comedy it is!

Pretty good! I had some laughs!
.... I'm a cat.
This was a fun bit of madness, by the way.

yes. Yes you are. And a female one at that. 
Glad you enjoyed all the madness... I was going to have Doctor Derp at some point say "meow, see. Meow. Yer a good kitten, see, but I'm top cat around here." But I couldn't find a place for it...
That title... That title is amazing.

Always room for a sequel, eh?
3796854 Hm... That IS true. I was kinda bouncing the idea around in my head. Perhaps I will... Depends on if inspiration hits me or not.
Well this was great.
