Original Commentary
Terrence is writing this arc, thankfully. I have my hands filled with ND right now. When he wrote them, the first and last were in order, the rest were in a random order... so every time I'm about to start one, I'd have to ask Terrence is "the comic about so-and-so next?". But, in the end it all worked out, and for the most part the scripts are there.

Is Brisbane totally regretting not saying "Yes" then going out the next say to get gift cards for everyone? You betcha. -Isabel

Modern Commentary
So, Fibber McGee and Molly had one plots, with two variations: "Everybody comes by to visit the McGees, one at a time" and "The McGees go out and visit everybody".

Basically, a character shows up, they do their schtick, briefly touch on the episode's main point (eg. Fibber tries to bake a pie), and leave. Then the next character shows up and we repeat.

This is that kind of thing. We've got the frame of the story here. Then we come up with as many relevant gags as we can on the subject and choose the five best. Which is why we didn't have a running order until much later in the process- Terrence
