C-3PO having a silver leg isn't remembered because he's remembered as being all gold. Most shots of C-3PO are from the torso up; not his whole body. He rarely ever walks as the suit looks clumsy.
Pikachu never had a black tail. I didn't remember it being that way.
"Luke, I am your father" is far more memorable because "No, I am your father" lacks the context.
The translations of the bible having different words are because the bible has been translated hundreds if not thousands of different times from language to language.
The original brothers Grimm version of Snow White does indeed say "mirror, mirror on the wall..." Many people would likely have seen Disney's Snow White when they were Children and wouldn't remember it verbatim. Not many adults are versed in that film, and if they were, they'd likely remember it accurately.
Though if you're looking for people randomly forgetting things and remembering it differently, look no further than Trump's supporters vis-a-vis his political ramblings.
In all of these situations, cultural perception plays a large part in how information is communicated.
