Just want to verify this: Coolant in the oil can only come from 3 places: (assuming you didnt pour it in the oil fill hole)
Cracked block
Cracked head
Blown headgasket
I bet you'll never guess why I'm asking

You are correct. Sorry you have to ask this question. Also if you have forced induction you can lift the heads with too much boost and get coolant in the oil that way.

Question: This is my first new motor, should the oil be pretty dirty the first time you change it? Like moderately dirty? I'm not sure if I'm seeing milkyness or just new motor break-in stuff.
