Hmmm...

I was thinking...what's the oddest AU CSI fic you've ever read?  Particularly G/S, but not necessarily.  I don't mean so bad that it's AU--I mean so good that it's believable AU.  And not just a simple what-if fic like "what if Grissom accepted Sara's dinner invite in Play With Fire"--I mean something strange, something you'd never thought of, something they'd never even think of showing on screen, and yet is worthy of it.

Any thoughts?
