So I've finally decided to actually learn how to use my art tablet that I've had for a few months, this is the first thing that I've used my tablet with, though it was still mostly refined with a mouse and the path tool.
I've had this joke ready to be made into a comic for almost a year now, I remember trying it out on my niece and nephew(they're both kids), and for about 5 or 6 months afterwards you could not mention a knock-knock joke without them trying to pull this. It became very annoying, so I sympathize with Trixie on this one.
My Little Pony: Friendship is Magicİ and it Characters both belong to Hasbroİ.
Can't get THAT back ever again.
Womp,womp whomp whomp waaaahhhhh......
I can't be sure Derpy didn't do that deliberately.
