Ever since I was about 10 I have removed the stringy white bits attached to egg yolk before I use/eat said egg (you have to remove it when it's raw). It looks like umbilical cord (which I guess it is). I swear I found a bit of the "string" in a cake when I was 10 which I think started me off. I am the only person I know who does this and everyone else thinks I'm odd! Anyone else!?
