More brains than a cuckoo clock?

          "Come, come, Jeeves. Would I start pressing gloves to my lips at the moment when I was about to pinch a policeman's helmet?"
          "Apparently Mr. Pinker did, sir."
          I was on the point of explaining to him that what old Stinker would do in any given situation and what the ordinary, normal person with a couple of ounces more brain than a cuckoo clock would do were two vastly different things,when I was interrupted by the re-entrance of  Gussie.
