In the closing tag, Lacy Gorensen and Sarah Chalke re-enact the opening of the Patty Duke Show. In the split segment of the two on Roseanne's couch, Gorensen moves her arm over too far and her hand is cut off in the picture.
This was intentional, to "poke fun" at bad split screen editing. On another note, Sarah Chalke's leg does the same.
