Brown Eyes and Red Eyes
There is an island of monks where everyone has either brown eyes or red eyes. Monks who have red eyes are cursed, and are supposed to commit suicide at midnight. However, no one ever talks about what color eyes they have, because the monks have a vow of silence. Thus, no one knows their own eye color; they can only see the eye colors of other people, and not mention them. Every day, the monks enjoy a silent brunch together at a round table.

Having acquired this new information, something dramatic happens among the monks. What happens?
