-An unknown word to describe something unknown.
-An example of why words just are what they are. There's no reason why mile wouldn't be klorp instead. (It just happens to be that way.)
Randy: "The sign says sixty miles to Camden. I wonder why they call it a 'mile'?"
Earl: "Well, because that's what it is. What else are you gonna call it... a 'klorp'? No one would know what you're talking about."
