I love the luxury of her apartment, and by G-d she was a work horse, rest her hard-working, totally Jewish, fearless, Israel-loving soul.
She always did talk about working on her jokes, writing them, crafting them and now this article shows a little piece of how she worked-thousands and thousands of index cards, with the subject matter ("travel, comedy, cooking"), and then the joke once it was perfected.
I remember hearing Seinfeld talk about the process of writing a joke, and how one joke took him a few years to finally complete.
Comedy is a science-not an accident.
