I have been toying with the idea of changing subjects when I am in Cambridge. Natural Sciences sounds terribly boring and no one interesting that I know of ever graduated with a degree in Natural Sciences from Cambridge - they all have pretty exotic degrees.

Bertrand Russell read Mathematics. Stephen Fry did English literature. You can argue that Stephen Hawking might give the occasional lecture on that subject (he is actually a professor of mathematics apparently), but he actually studied in Oxford, so that doesn't count. And Newton was in the university before they actually had Natural Sciences, I think. Hugh Laurie did anthropology and archeology.

James Bond has a degree in Oriental Studies.
