That’s not how knock-knock jokes work, Rey!
If you haven’t seen The Rise of Skywalker, here’s how it ends. Basically, there were three movies of utter nonsense that not even the most diehard fans could justify. Rey Skywalker, granddaughter of Darth Sidious, returns to Tatooine, Luke’s home planet. She then buries his and Leia’s lightsabers before meeting a random lady in the dessert.
The brief dialogue between the two is awkward at best. The lady asks Rey who she is, to which she answers, “Rey.” The lady asks her to clarify (“Rey who?”), which is completely unnecessary since this lady wouldn’t know her anyway. And, to answer this meme’s question: yes, she is the surname police.
