Probably not quite what you mean, but your parenthetical reminds me how many years ago, I had these people I hung out with online; we had a bunch of characters we tended to randomly throw together in really ridiculous part-chat, part-RP things. Somehow they all ended up living in some house in the boondocks. There were OCs, literary characters, movie and TV characters, and everyone was pretty much always at everyone else's throat and having a nervous breakdown [the characters, that is, although the RL group also fell apart with little glory]. =P
