Hey Pappy, this is one of my favorite movies and as you pointed out - one of the best scenes ever. Burgess Meredith and Jack Lemmon are so perfect together.
But did you see all the continuity issues? At one point Meredith's cigarette is out of his fingers, the next instance it is back in his fingers and half smoked. His beer and cigarette change hands frequently, and the cigarette changes length almost every shot.
Not a criticism, I love the show and the scene - it just adds to the fun for me.
