Funny clip with Shelley Winters + Annie Potts

I have the Ultimate Collection of Johnny Carson on DVD that I was watching today, and I so remember this. I only saw this movie once, but I kept wondering if Shelley Winters really remembered Annie, and if she was really holding an umbrella at the grave site as Shelley said (when she finally remembered her) I couldn't find that clip on Youtube.
