The grandfather of my best friend from high school had the privilege of having Feynman as one of his seminar instructors whilst at Cornell. In fact, he remembered the famous lecture described in &quot;Surely You&#x27;re Joking&quot; where Feynman showed up to teach after getting a black eye in a bar fight the preceding weekend.<p>According to his account, Feynman walked into the lecture hall, turned to face the crowd (at which point, his black eye was noticeable), and asked &quot;So... any questions?&quot;
