I haven't seen the episode, but whatever the fire alarm is supposed to do in real life now, doesn't really apply to cartoons. People are just gonna do what is known, rather than probably be politically correct about it. But you make an interesting point about the aftermath of the fire alarm.
Ahh, I see. Though I figured it's possible the Art School still has a pretty old fire alarm system in use, since they've been having financial troubles. But yeah, the whole fire department absence thing surprised me; after all, a "G.I. Joe" PSA described why you shouldn't pull false fire alarms.
When you make a new page, please make sure it already links to from somewhere, or find a page afterwards where it can be linked. Otherwise, it's essentially lost. I'm sure this may sound more work than you'd want to do, but it pays off in the end.
