Finding Funny League Story (Dr Mundo feature)

I read this story awhile ago on here or reddit regarding a funny duo with a Dr Mundo. I believe he was with a mid diana or such (female mage/champ) in which every time he got a kill or assist he would all chat "Is Mistress pleased with Mundo?" or something near that. I mentioned the story to a friend recently but cannot find it and want to prove I'm not more crazy than I am.

Anyone ever see this or know where it is posted at?

Thanks!
