There's one thing in that episode that made me split myself laughing, allthough it doesn't make any sense at all. When George is helping his father fixing the screen-door, you can see kramer taking a picture of them, and telling Frank to move closer so he can fit both them and the screen-door in the picture.
Does anyone have an idea of what this is all about, I always expected a follow up on that in the plot, but there was non.
