The studio audience from a show back in 1992 thought they were attending a regular taping of The Oprah Winfrey Show.
Instead, they were part of a very revealing exercise in racism.
We called it the "Blue-Eyed vs. Brown-Eyed Experiment."
The purpose: to demonstrate how easy it is to learn prejudice.
Guest Jane Elliott started this exercise in her third grade classroom in 1968 after the assassination of Martin Luther King.
Jane tells the audience that brown-eyed people are more intelligent than people with blue eyes - and they start to believe her!
