===Journal===
Someone linked to it in an r/HPMOR discussion of time travel. I bookmarked it and read it about a week later, on September 30th 2012, in no more than 9 minutes.
Not perfect, but pretty bloody brilliant nonetheless. Very short, but made me grin and then laugh out loud in anticipation of certain events.
