Actually, the shot of Rusty's shrimp cocktail changing from a cocktail glass to a plate is not meant to be seen. You can't see it in the original widescreen version, the lower part of the scene is cut off. For the pan and scan TV version, they use a little more of the top and bottom of the film, so the change is apparent. The cameraman was composing for widescreen, not 4:3 pan and scan. Another movie like this is Terminator 2. When Arnold smashes the pay phone to get a quarter, in the TV pan and scan version, you can see the payphone is already smashed before he hits it. You can't see this in the original widescreen.
