ITAW/P for knowing the parody of a work before the original work?

For example, a teacher I know is concerned that her students have heard fractured fairy tales without ever hearing the original fairy tales they're based on. Another example: I loved Weird Al's "Amish Paradise" for years before ever listening to "Gangsters Paradise". The difference is I was aware it was a parody, and the students don't know the fractured tales aren't the real thing. Any word for either or both of these cases?
