Hal's Birthday gets a 9/10
The best part of the episode was the boys' plot. With a common enemy/complaint, they actually can be nice to each other every once in a while, which is good to know. Piama's intro, however sudden, also helped reaffirm that Francis hadn't really changed at all -- he's still quick to act and slow to think, as usual.
I didn't really have any problems with the episode, except for maybe how Piama and Lois don't get along, and that makes for some very good humor later.
