SPN Fic Prompts?

No one is probably online and I'll likely regret asking this anyway but...

Dean and Castiel prompts anyone? I really *really* want to write something short so I can feel like I've accomplished something. My next wing!fic is going to turn way longer than I expected and the Sam AU is, too. I'd like something small I can finish this weekend to boost my mood.

Any ideas? No slash, please. But I guess anything like angst, drama, h/c (though nothing extreme because you know how I feel about that sort of thing), or maybe something sad, and I suppose I could try humor, though I'm not feeling too funny.

I really need more icons...
