When Cas got the Cosmo, I snorted. When he said, "Excorsing demons is such a turn-on," I spat ice cream all over my computer. But when he said, "I... wish to... examine the restroom," and ran off to peel out of his undies, I literally, honestly peed my pants. I haven't read anything this funny in so frigging long, I think I strained a major muscle group laughing. And then the end just slayed me with adorableness. I'm totally going to go rec this.
