Joy = Puppy

Like most puppies, Archie assumes that anyone he meets, regardless of species, must be as interested in him as he is in them. That's generally true of the human species: who among us is immune to the cuteness of puppies? Archie is attending puppy class in large part to make sure he isn't an annoying asshole in public.

As I mentioned a post or two ago, the Beast seems to think that whatever Archie wants is just fine by him. But who uses a cat as an arbiter of decency and good behavior? Cats are aliens, have no doubt about this. Mimi, who by necessity inherited the mantle of resident CrankyPants from Harry, has other ideas. She has a remarkable level of tolerance for puppy bumbling but she does have her limits. 

Azza has no limits for puppy bumbling. She exploits every excuse to incite the puppy to even greater heights of silliness.

I give you this as evidence: Azza and Archie collapsed together after an excess of exuberant and joyful play...
