No Relation
The story about Noah and his Ark originates from religious texts. Depending on which book you read, either the entire world was flooded or only Noah’s people were exposed to the torrential rain that flooded a particular region. Anyway, the story has been talked about so much that even non-religious folks know who he was.
In this episode of Animaniacs, you can see Buster and Babs Bunny walking into the famous Ark. Before doing so, they introduce themselves as having no relations to Noah, who is visibly relieved. After all, you can’t have a pair of bunnies doing what bunnies do on a kid’s show!
