Reminds me of the English prof telling his class

The professor was one of philosophy, his name was J L Austin (1911-60), and he was delivering a talk in the US at Columbia. The man in the back row was Sidney Morgenbesser (1921-2004), and he just died recently. Even funnier when you know who said it first ... I've usually heard it as "Yeah, yeah".

Austin's book, How to do Things with Words, is a classic and quite easy to read. It deals with speech acts, and influenced John Searle in his work on same.
