I was watching an episode today ( not exactly sure on what episode, I benge watch) and mabel screamed " GRUNCLE STAN" and that got me thinking, Stan isn't their uncle but their great uncle. Stan has never mentioned having a sibling, but he has to have one to be a great uncle. I am a firm believer in the Stan twin theory, but I have to remind myself that it's a THEORY, so sometimes I have to think outside the theory. Where is stan's mysterious sibling? If it's one of the twins grandparents, why has no one mentioned it? Just my random rambely thought for the day :P. Please comment, and tell me if I missed somthing or im crazy (like i really need anyone to tell me)

In a tale of Stans, there is Stanford, Stanley and another child who looks exactly like Mabel and Dipper. Stanley and Stanford are both great uncles because their third sibling is Mabel and Dipper's grandad.
