Continuity mistake: Ruth's pink checklist never looks quite the same throughout the movie. When she crosses "FAMILY" off her list, her line is crooked, but the next time they show the list, that line is very neat and straight. You can also see differences in the circles that she draws around the numbers. Sometimes the circles intersect the dashes, and sometimes they don't.
Continuity mistake: When Ed Begley Jr. is with his secretary on the photocopier, it takes copies of his hands on her rear. Later, when Roseanne finds these pics, there is a ring on his finger that wasn't there before.
