There's lots that we do remember, sometimes odd things like your example, though I'm sure you must have repeated it a few times as well. But there's so much detail that we don't remember at all, and even our childhood memories just become memories of memories - we remember some event, but we slowly forget the exact details, they become fuzzy.
People do stuff like that all the time, bringing up past memories in spontaneity. The brain absolutely does remember things it "doesn't need".
