I would never say that Jo Anne Worley was annoying*, but I saw something this morning on $25KP that made me think of this thread. In the Winner's Circle, the category was THINGS THAT HAPPENED IN THE 70'S. She said, "John Lennon was, uh, ..." I think at that point she realized that he was assassinated in 1980. Then she said, "Johnson was President." No, that was 1964-69. Amazingly, the contestant got it. (She said, "nineteen seventy-one," or some other year from that decade, and they accepted it.)
