Rita used to be a shitpost meme on /b/, and and had a few rather big threads here on /co/ somehow.
And just then, only a few weeks ago, /trash/ had 3 threads in a row about Rita, all of them literally reached the max 300 post limit. That's quite impressive.
If you want to see them, here they are, thanks to desuarchive

But really, the whole reason I shared this is because this one cartoon fox managed to cause shitloads of discussion. No one even gives a shit about the actual main character. It's somewhat amazing.
