In our house, we have a little catchphrase that we utter if we see one of the cats doing something like rolling off the arm of a chair, or attempting to jump up onto the kitchen table and missing. It goes "grace and elegance, thy name is Cat." (or alternately, depending on our mood, "so much for 'feline grace'".

That it happens frequently enough to have multiple catchphrases associated with it is noteworthy. :-)
