If you put a work out in the public space, it will be parroted, parodied, sampled, remixed, etc. If you're lucky, because that means it has meaning to someone else. As long as it's not some sort of attempt to fraudulently pass something off as the original, I've got no problem there. You can even parody it yourself twenty years later, just don't pass it off as the original.

You raise a good point - I've lost count of the number of pop-culture items that have been introduced to me via parody (particularly from the Simpsons) and none have tainted or ruined my eventual experience of the real thing.
