In an old vaudeville routine, a straight man asks his partner, "Who was the lady you were with at 7:18 pm on the night of July 23, 1903?" to which the comic, scratches his head, looks puzzled at the audience, then answers, "That was no lady. That was my wife."
The audience laughed partly because of the improbability of remembering specifics of an exact date and time, and partly because of the unexpected reply.
When Jill Price is asked such a question, unlike vaudeville audiences people don't laugh at all. They are astounded by her memory. She can recite details of the days of her life since she was fourteen years old, be they sad or happy. The details can be what she had for dinner or saw on the TV.
