Is a Double-Yolked Egg Lucky or Unlucky? [POLL]

My wife and I have been making a lot of deviled-eggs lately and recently we found a double-yolked boiled egg.  We still made it into a deviled-egg anyway.  My wife was told by a friend that they are good luck, so I looked it up. I got conflicting reports.

According to The Encyclopedia of Superstitions by Richard Webster:

Double-yolked eggs are believed to be a sign of good luck. However, in some parts of Great Britain a double-yolked egg is a warning of death.

According to Baby Lore – Superstitions and Old Wives Tales from the World Over Re: Pregnancy, Birth and Motherhood by Rosalind Franklin, Romany Gypsy folklore says:

Finding a double yolk in an egg means someone in the immediate family is pregnant. If she already knows she is pregnant, it means she will have twins.

What do you think?
