The cloth tie Monica is wearing as a necklace has dark patterns that randomly change locations from shot to shot.
Ross's answer "Queen Victoria" is technically incorrect. Queen Victoria holds the record as the longest reigning British monarch (that is, monarch of any one of the historical or current kingdoms of the British Isles - England, Wales, Scotland, Ireland, the Kingdom of Great Britain, or the United Kingdom and its successor states). She reigned from 1837 - 1901 as monarch of the United Kingdom of Great Britain and Ireland. She was never queen of the Kingdom of Great Britain (or "Great Britain") which existed from 1707 to 1800. The longest reigning monarch of Great Britain was George III, her uncle.
This entire argument is redundant, as the Ruler of the United Kingdom also includes reign over the land of Great Britain. Queen Victoria reigned over the United Kingdom (which includes the Kingdoms of Great Britain and Ireland) for 63 years, over three years longer than George III.

At the very end of the episode, when Monica falls down the stairs in her attempt to apologize to Mrs. Green, the green safety mat is visible where the steps should be.
