LOL!
I haven't watched Season 2 yet (I've been waiting for it to finish, same with Shogun!), but as a comic book artist, this was one of my favorite jokes from the comic, and I admit, I employed similar tactics when I was drawing my first graphic novel, and some scenes I wrote I was able to use this "trick" to finish the pages sooner, especially talking scenes lol
The fact that they managed to adapt it in a way that maintains the meta-commentary, and applies it to animation is great and fricking hilarious! The Simpsons also did a similar joke ages ago that cracked me up back then too XD XD
