'Scuse me. Have you seen my yak?

So you are sitting in the back of a truck, it is sunset, and you are busy trying to figure out what those silly dogs are doing based on their radio signals.  Suddenly, up the road, just on the other side of a small hill you see a lumbering, greyish white THING waddling back and forth.  You cannot see its face, just the torso.  You think

A) Oh, here comes a rhino up the road

B) Weird, that's a really small elephant

C) Is that a yak????

C.  Definitely C.  Because that's logical, right?  

I blame the malaria medication.
