Not that I don't have other things to write, but leighleighla put the idea out there and now I'm mooching it.

Buddy Cop Prompt!

Give me a duo that you'd love to see from the following fandoms and I'll do my best to put it together in the form of some comment fic. (General prompts accepted as well just for the hell of it).
