This shouldn't be necessary, but just to be on the safe side I would like to make one thing perfectly clear:

Professor Stephen Hawking is a brilliant, courageous, remarkable man... he is not, however, a gangsta rapper.

If any of this came as a surprise to you, I suggest that you have a talk with your parents; they have some bad news for you about the Easter Bunny.
