As a child, I thought that the yolk of the egg was the part that would have become the chick if it had been allowed to mature - probably because it was yellow. I wouldn't eat egg yolks because I thought I was eating a premature, liquified chick. One time I refused to eat my birthday cake because I saw my mom put an egg in it. Even after I finally believed the adults that were telling me it was just the food sack that would have fed the chick, it took a long time before I'd eat the yolk.
