I am eating some soy chicken nuggets, and it reminded me of my days back at Mcdonald's when I would order chicken mcnuggets. I recall that most of the time, the nuggets were white, but then there would always be a few dark colored nuggets mixed in. I could never figure out why. I know this happened a lot because I recall friends noticing this too, and it happened at more than one Mcdonald's. I'm assuming it was different body parts from the chicken, but uh, I'm not sure... and so that's why I'm re-hashing this long forgotten mystery.
