Christ, what is wrong with you people ? An egg is an egg. A conjugating cell which unites with another of like or unlike character to form a new individual.
Most talked about is the chicken's egg, usually white or brown in colour and shaped like an oval with a fat end. Alot of people eat them, but vegans don't eat them.
And people who don't like them don't eat them either.
Fred: What is that ?
Tom: It's an egg !
