2. Joaquin Phoenix
Phoenix and his late brother River didn’t change their surname, that was their parents’ doing. The reason might be in the surname itself: Bottom.
1. Whoopi Goldberg
Speaking of such, Goldberg, who was born Caryn Elaine Johnson, got her first name from the cushion of the same title. “If you get a little gassy, you’ve got to let it go,” the comedian and actress told the The New York Times. “So people used to say to me, ‘You’re like a whoopee cushion.’” Goldberg is her mother’s maiden name.
