I would like to state that A chooses to treat the pooches after a trick or some sort of show, which clearly favors Miss M. I, on the other hand, give treats whenever they look cute, which is clearly in favor of Mr. B. The snooty Miss M and A are the intellectuals of the house, watching foreign movies with ironic humor and reading things like books, while Mr. B and I are very much the simpletons of the house watching instant classics like the new Muppet movie and reading things like the comics page in the newspaper.
Poor Mr. B, despite his inferior intellect, he still tries very hard to learn new tricks. It took us over a year to teach him down, on top of his other trick of sit, but A wanted to push the boundary and add wave to his repertoire of tricks. Now Mr. B is so confused that he cannot tell if he should be waving, sitting or laying. Sometimes you can see that single wheel in his head spinning so slowly as he tries to figure out the trick that will get him the morsel of treat.
But like his old man, he is not quite bright and not a quitter and he will try until he gets it right.
