OMG, these are just hilarious!
I'm trying to think up some, but the only thing that's coming to mind (and I'm just about to fall off my chair laughing over it, even though it's really not THAT funny) is Batman/Robin - see, if I put that in my series, given the fact that everyone seems to think that Clark is Batman, then you end up with a pairing that's really Superman/Robin and... I'm sorry, I'm choking with laughter, here.
Maybe I've just lost my mind?
