Or me, who arranges them as close to rainbow order as possible (brown is sorta close to purple right? No? Oh well), eats the extras, then eats the rest in rainbow order.
I always eat 2 M&M's of the same color but on either side of my mouth.
If I mess something up (2 on left side, or green on left red on right for example) I have to even it out for the next bite (2 on right side, or red on left and green on right) otherwise I'll lose my "M&M streak" and I don't wanna eat em anymore.
