Continuity: Due to the effect of the red glow on Kramer's eyes, he confuses the pitcher of tomato juice from Jerry's refrigerator for a pitcher of milk, pours it into the cereal, then gags and promptly tosses the contents of the bowl into the trash beside the fridge. In the close-up he tries to wipe some of it off the wall, but there's still a huge red mess left on the wall, in the trash, etc. In the next wide shot of Jerry and Kramer, the trash and wall are spotless.

Continuity: When Kramer spills the tomato juice all over Jerry's walls, he grabs a light colored oven mitt to wipe it off. In one shot he wrings out the sopping mitt over the juice pitcher.
