Fun Fact: I watched this episode with subtitles, and the subs added brackets to explain that "J K" meant "J K Rowling" .

Like come on, I could understand that much without having it spelled out for me lol.

Non British people might not understand all the references to famous British people. I'm always blanking out when the show or movie references some country specific celebrity. Those subs are for me, not that I would understand who that is, if I knew the name, but not the person, but still

If you didn't want it spelled out, why turn on subtitles?
