All that is required to be nominated for a Nobel Prize is that one person with some particular qualification in some particular field (varies by prize type) nominate someone.
It should impart perhaps a little more prestige than being nominated for the Florida Recall Governor's race, but not much.
Several years ago, three men won the Nobel Economics category, & split the prize money for their 40-year study of world economics. All three declared the system a game, such as playing poker or chess.
Two of the men were Americans, living in different areas of the United States, I believe, and the third was a European. I've never been able to find anything else on them - lost the news clipping & can't recall their names.
