Gotta love the names Dean comes up with. "The ghost of Christmas screw-you" is my favorite here, I think. Other than the classic "nerdy dude with wings", because really, that's a classic AND an accurate description of Cas.
Out of the two brothers, I prefer Dean. Some people seem to think that that means that if you prefer Dean it means you dislike Sam, and vice versa, but no. I adore Sam, and this pin just made my heart break for him.
