There's a famous saying about how an apple a day keeps the doctor away.  I don't know if that's true or not, but when I was a little kid I thought it mean that apples worked on doctors the same way that garlic works on vampires.  Like it repulsed them or something.  I figured all you had to do if a doctor was coming after you was pull out an apple and they would shirk away in fear.  

While I have to say that would be pretty cool, I guess it could backfire on you big time if you collapsed and needed CPR or something, but you happened to be holding an apple at the time.  Then the doctors couldn't get at you because of that apple and you'd be screwed.

Oh, and now that I think about it, if I were a competitor of Apple, the giant computer corporation, I would totally play up that my products were to preferred choice of doctors everywhere.  Because, you know, their products drive doctors away.  Android should totally hire me right now to head up their marketing wing.
