I think all of us have extraordinary mental powers in certain limited conditions. One of mine is the ability to remember which CDs in my collection are missing out of their cases. I realized this when I came across a pile of CDs, and was incredibly happy that I could go through this mental list in my head and check a few off. (Another former list member was Nirvana's Nevermind, which, for years, I was quite torn up about losing, but then one day opened the case and found it there, all scratched up and covered in coffee and paint stains).
These powers manifest differently for different people. I know several people who can produce an exact quote from The Simpsons to fit any situation, along with the entire plot of the episode the quote came from. Others can identify any of tens of thousands of songs from hearing only the first few seconds.
If only these Rain Man powers could be put toward something useful, then ... well, the world would be a much less interesting place. So screw that.
On a related note: I usually don't have any strong feelings about celebrities, but I truly dislike Jenny McCarthy. Her ignorant but loudly spouted beliefs about autism and vaccinations are literally killing people. She should go back to blabbing about psychic Indigo children from another dimension instead of pretending she's a doctor; at least then, people would be more apt to realize she is batshit insane.
