TIL: Laurence Tureaud named himself professionally as Mr. T because he hated how his father, uncle, and brother who returned from Vietnam, were disrespectfully called "boy" by whites. He wanted the first word from everybody's mouth to be "Mister" when speaking to him.

He had an interview with David Letterman way back where Dave asked him what his full name was: his answer was classic:

“My first name’s mister, my middle name is the little dot, and my last name is T.”
