For a long time I have asked people in what order they ate their M&M's candies when they were kids. Basically, there are two types: those that ate the ugly ones (brown, tan) first versus those who ate the pretty ones (red, green) first.

I don't think I have never met anyone who didn't remember, and people who ate them in any order are rare.

I always saved the pretty ones till the end. Sometimes I thought red was the prettiest, sometimes the green.
