I guess someone should tell the ESRB about the nude patch for The Sims.
Edit: More detailed information here -

Mostly, this is just laughable, but I'm slightly worried about this: "Furthermore, the ESRB calls on the computer and video game industry to proactively protect their games from illegal modifications by third parties, particularly when they serve to undermine the accuracy of the rating."
