Why someone might think you're crazy when you're not

At the end of a long day a 96 year old lady stopped me to tell me a joke. Then she told me a funny story about something that had happened where she had lived previously. (this might need you to read the story outloud for full effect) There was a lady living at the same place whose name was Alta Holmes. Alta Holmes was moving out to another facility. Ivy, my friend, said to someone that morning, "Alta Holmes is moving today." The man she was talking to said, "Don't be silly Al Capone has been dead for years."
