I fell out the window of Olaf's room in Diggy's metro server.
But I've already posted about that.. so..
before that I was exploring a cave and stepped down one step only to find that there was a two or three block wide "crack" through which I fell into darkness. I was almost dead and trying to move more porkchops to my quick inventory when I was cornered by at least three creepers and four skeletons. D:
