"Can we have a puppy instead? Please, Daddy? We could call it Sammy too, if you want."

Priceless. This series is great - it's gonna hit all that much harder when you get to the inevitable changes that are coming....

I also love John's way of teaching Dean, even now, through military metaphor. In all these, it's a great way of foreshadowing how he turns into the "drill sergeant" and Dean becomes his platoon - great choice for pointing up these insights.
