That reminds me of his appearance in a Simpsons episode. At the end he said, “And now I’m going to go back to whatever it is that I do.”
I understand asking, “What exactly does George Plimpton do?” was a running joke whenever he made an appearance, but it’s one I still don’t understand. He tried things–like trying out for football and baseball teams–and would write about his experiences. To ask what he did is to imply that writing isn’t a profession.
