Well, I am not a list nut, but I have a certain way that I eat M&Ms. If I pour some in my hand, I have to color code them into groups and then count them and eat the odd ones. Then when I have the same number of each color in my hand, I am ready to eat them. Do I have a problem? =-)
I like eating them in the movies, because then I can't arrange them and don't care.
