Loved the joke where Roger yanks on the chain of birds and instead of the birds flying, it breaks their necks. And then... "Stan, dinner."
Come to think of it, Stan and Roger had great chemistry in this one, like the jokes about not listening and "I don't know what a metaphor is", among other moments.
Steve and the cat didn't do it me; I've seen that kind of plot before- a cat acts nice to someone and attacks someone else.
