A ton of times these high profile people will be giving a press conference or an impromptu interview to whoever and they take a ton of rapid fire questions. So many times someone will slip in a question like 'do you think the end scene was symbolic of the protagonists suppressed desire to felate their grandma wearing a strapon?' and they're like 'uh yeah sure I mean if you want to interpret it that way I guess' then move on. Then the next day you see stories like 'such and such actor said he wants to fuck his grandma' and then it spirals from there. I just ignore pretty much everything I read these days tbh.

Pearl Jam said they got their name from psychedelic jelly one of their grandmothers used to make. That seemed to stick for years. Later they clarified that it was just a joke but the grandmother's name was in fact Pearl.

My theory is that it only needs be true once on a TIL and then the rest of the internet will believe it to be true.
