SCP Foundation

Reading the lolFoundation canon, and how it's essentially the "goofy apocalypse" universe, I got a meta idea; specifically, a skip describing a phenomenon where cities are spontaneously replaced with their lolFoundation counterparts for a week or so. Given what happens in the lolFoundation, the canon's actually competent, less loony Foundation seriously panics whenever it happens, but regularly contain the problem… because the locals have caught on to what their canon is. For example, a mother blithely accepting her son being eaten by a cognitohazard, because "we were bit parts anyway; he'll be back when it escapes again." Needless to say, the Foundation gets really, really weirded out, especially given how ambivalent the locals are to their presence (on the one hand, reality's about to distort again, on the other the Foundation is about to do something badass - in their experience).

I think you might be better off having some Sites replaced, rather than cities, so you can focus on the contrast between the serious and lolfoundation realities without having to address the issue of public exposure (or I guess set this in the Broken Masquerade canon).

A meta article about the real foundation having to deal with the antics of their goofy counterparts could be entertaining if it were done well; I think you could play off the Foundation personnel's ability to grasp their situation and start messing around with the boundaries between one set of laws and another (kind of like Who Framed Roger Rabbit?). I think playing it straight and letting the humor be low-key would be better than over the top goofiness. If you can come up with some clever aspect - some glitch in physics that explains why the lolfoundation universe keeps running even though everyone's so incompetent and a plot that makes it relevant - this could make a good SCP (though it would probably be much easier to write as a tale).
