Bill Simmons has had a running thing called the Reggie Cleveland All-stars which can be explained as:
a list of sports figures whose names would seem to indicate that they are of a different race or ethnicity than they actually are". Its namesake? Cleveland, a 1970s-era pitcher whom Simmons just assumed was black until learning otherwise when he joined the Red Sox.
I think it would be funny to do for all celebrities/famous people.
I randomly thought of this as I was listening to Brown Eyed Girl by Van Morrison
because I always assumed he was black only to find he is a old Irish dude.
