Which came first? The chicken or the egg?

Okay, so this question is just for laughs. But it might make a good discussion, regarding everyone's personal opinion on the subject. I personally believe the egg came first, and that something prehistoric laid the egg. Over time, nature evolved, and a new creature was born. Something that resembled a chicken. And farmers bred these creatures, until the chicken itself became it's own species. What about you? How do you think it happened? Do you think the chicken came first? Or the egg? You can explain as little or as much as you want to. Everyone's opinion is respected, o go on and give me details! =D
