The Jon Stewart of Cats

Given his expressionless (though some may say it looks pretty dour) look on Diego-san's face it's likely he doesn't have much of a sense of humor (let alone appreciation for humor). Yet some of his behavior is so goofy I gotta believe that he's putting me on.

I'll come home only to find him perched high atop the refrigerator. He climbs into various places in the house that the other cats wouldn't even think about. He's amusing to the extreme and somehow I think he knows that and knows that I know that.
