Eggs

I don't know why I keep thinking about this, but I have probably thought about this for the past five years.  I've always wondered what would happen if you baked an egg.  I love eggs.  Hard boiled, over easy, scrambled, fried, poached, truffled, nogged, fertilized... but you never hear about a baked egg.  Why not?  What happens to it? I need to just do it and find out. And for some reason I've never questioned what nogging an egg meant.  I question it now.
