I don't know what is going on in this picture. The only thing I could think of was that this little guy is looking up (ba-zing) at his large friend. Weak. I know.
Or he's crashing face first into this fence, which is sad and funny at the same time.
Its a superb picture of a mini pony, and that warrants it a place as the MPotD. If it was hurt when it crashed into the fence, then it totally deserves the prestige (I guess) of being the MPotD.
