A slight proof that human might be existing in Pony world. 

Almost @ 2:47 in the video Pinkie clearly mention that there lives a meat eating yeti in Yakyakistan. 

I think that might be a clue that a human is hiding in Yakyakistan and known as yeti between ponies who likes to believe romours and such as Pinkie Pie.

It's my opinion only but I wonder why no one ever thought of that possibility.
