Wag the dog
To quote a favorite movie: the dog usually wags its tail, but what if the tail wagged the dog? In our case, Sam not only wags his tail and the rest of us, but insists while doing so, that he should be fed grilled sausages mixed with al dente pasta. Hey, who is in charge here Sam!? OK, now off to get you some fresh lamp chops and then you will get your usual evening back massage. Would you like some perfumed oil with that?
