I Know Why the Caged Bird Sings
Maya Angelou mentions learning Tutnese as a child in the first volume of her autobiography, "I Know Why the Caged Bird Sings". She and her friend Louise "spent tedious hours teaching ourselves the Tut language. You (yack oh you) know (kack nug oh wug) what (wack hash a tut). Since all the other children spoke Pig Latin, we were superior because Tut was hard to speak and even harder to understand."
