American Dad!

Rip Harambe

I think that American dads production bible is used to make every episode, like king of the hills or bobs burgers. Like I think the writers and animators on American dad uses background characters and other storylines or one off lines as continuity to further the story telling almost like a never ending story. It is cannon that these things happened even in the later seasons, and I hope they are able to pull a ladybug story in the future.
