The Prompts of Yuletide Yet-To-Be

A mention of something in the comments of a post get my brain going in interesting directions. Yuletiders, did you know that Madness fics don't have to be of the 3-4 requested fandoms, but can be of any fandom in the current year's Yuletide? So, I thought, what prompts/fandoms would I have chosen, had I chosen differently? What might I ask for in the future (assuming eligibility doesn't change)?
