With enough people in a common area, I'd say someone is going land on Uranus occassionlly regardless of where it is and what topics (or lack thereof) are discussed. Also knowing that behind your computer nobody will slug you or haul you off in straight jacket, it's probably that much more likely for somebody to blow there steam on an internet forum.
The weird stuff here earlier this week, I think took just the right combination of at least one person being trollish, one person being a bit uptight (bad week at work/home?), FF moderators naturaly preferring a little sarcasm in response to an acusation - especially when in response to a whimsical thread, and a couple bad coincidences. That doens't mean your theory won't rise its ugly head though.

OK, I can be next.....of course, I'm so full of it, I doubt anybody would take my posts seriously if I did go postal.
