DH 18: The Chicken or the Egg?

There’s an old biblical studies joke–yes there are such things–that goes like this:

Documentarians believe that that can take a four egg omelet, and not only separate out each egg from the other, put each back in its proper egg, and  tell you which four chickens the eggs came from, but also that they can tell what each of the four chickens was thinking when they laid the eggs.
