Crack pairings, anyone?

I want to write something wacky. So.

Gimme a crack pairing in any of my fandoms (or crossovers), and I'll try and write you a comment ficlet with that pairing (unless it breaks my brain, in which case you pay for my therapy, and try again). Threesomes and moresomes okay too. As crazy as you like, try me.

If you want a fandom you're not sure I know, try me anyway. I just need to be familiar with the characters you want paired, and we should be good to go.

I'm heading to bed now, so I'll have to pick up the prompts tomorrow, if no-one minds waiting. *grin*
