Yeah, I saw JAWS 10 times in the theater (hey, that's what we did back in the 70's!) and I know I never saw that scene.

Now, the million dollar question that hasn't been asked:

Caltikfan (Ed), did you ever read the book?

I'd be shocked if you didn't, because that of course begs the question: how would you know about this scene that everyone agrees was only IN the book?
