Well, today I've read in ABC News (
http://abcnews.go.com/Politics/story?id=8195564&page=1) that Professor Gates claims to be Half-Irish. Then article says: "he found he was descended from an Irish immigrant and a slave girl".
Last slave girl to sleep with an Irish immigrant must have done in 1860. Assuming 9 months... Gates must be born in 1861 latest, which makes him 148 years old. His birth certificate must be even more amazing, than Obama's.
Something is unhinged indeed.
