"Why do you have to make such a kerfluffle out of it?" Crowley glared at Dean who stood, red-faced and furious, between two burly demons.
"Crowley," Dean growled. "You stupid piece of –"
"I mean, it's so petty! You prefer your internal organs on the inside. I, on the other hand, prefer your internal organs on the outside! Seriously, Squirrel, what's the problem?"
"Crowley, I'm warning you!"
"Dean. I try and I try, but you put nothing into this relationship." Crowley sighed. "I give up."
Nodding to the demons, he said regretfully, "Kill him if you can," and walked away.
