I don't surf Craig's List much...
...and if I did, I wouldn't put any time into the "Casual Encounters" section.
But since I've had this post brought to my attention, I have to ask:
Wouldn't that be a little off-topic? Nothing about it sounds casual. It sounds quite formal, I should say.
(Yes, I note that the linked posting is not hosted by Craig's List. I suppose that it's possible that someone else just decided to host it, since it likely would have been deleted by now. In fact, don't we all pray, and fervently so, that this is a hoax?)
