Celebrities Who've Really Said "Do You Know Who I Am?"

In 1987, the British philosopher Sir Alfred Jules Ayer came across a youngish Mike Tyson forcing himself upon a young Naomi Campbell and tried to break them apart. Tyson warned, "Do you know who the f*ck I am? I'm the heavyweight champion of the world!" Ayer replied: "And I am the former Wykeham Professor of Logic. We are both pre-eminent in our field; I suggest that we talk about this like rational men."
