De Niro finished about one year of high school. He’s a DUNCE!

Wikipedia:

Robert Anthony De Niro Jr. was born on August 17, 1943...
De Niro's parents... divorced when he was two years old after his father announced that he was gay.
De Niro was raised by his mother in the Greenwich Village and Little Italy areas of Manhattan.
Against his parents' wishes, his grandparents had him secretly baptized into the Catholic Church while he was staying with them during his parents' divorce.
Nicknamed "Bobby Milk" for his pallor, De Niro hung out with a group of street kids as a youth in Little Italy, some of whom have remained his lifelong friends.
He then went to Elisabeth Irwin High School, the private upper school of the Little Red School House, for the seventh and eighth grades.
De Niro began high school at the private McBurney School and later attended the private Rhodes Preparatory School.
He dropped out of high school at age 16 to pursue acting.

That's quite a few private schools for a child of 2 painters.

Bobby Milk is also an interesting nickname.

Already he was a loner, painfully shy and given to retreating into long silences. After school he took to wandering around the streets of Little Italy, past the sleazy bars and pool halls, and he joined a street gang on Kenmare. Gang members nicknamed him Bobby Milk, “because he was pale and strange as milk.”
