From The Guardian‘s quite good (!) obituary of Elizabeth Anscombe:
She was notorious for a forthright foulmouthedness which was only enhanced by the beauty of her voice. When presenting a paper on pleasure, she distinguished extrinsic pleasures – things we enjoy because of the description they fall under – and intrinsic pleasures – things we enjoy regardless of how they are described; and she cited, as an example of the latter, “shitting”, strongly pronouncing the double “t”, and with such sternness that her academic audience were too daunted to laugh.
