"Bad Machinery" is more than good

It's great, actually. The Nov 12 episode has a teacher who has just bumped into one of his students in civilian life, at the farmer's market, while shopping with his wife. He's upset that she introduced herself:

"Why do you think I wear dad's old glasses and a dead man's suit to work? They can't know you're human. The kids got to think you're a mad old robot."

This kind of chagrin, people going ape over little things, is one of the things I like about the comic; the other is the way characters tease each other creatively.
