Occasionally I'll find a blog comment that just brings all other thought processes to a pause. It doesn't have to be terribly profound -- I'm not talking about thoughtful quotations from great philosophers -- but rather, the normal snippets of conversation you might hear in an elevator, a slice of somebody else's life that you parse and parse but just can't absorb completely.
Here's my most recent discovery (name redacted).
I tried flying 737's as part of a "virtual airline" back when I played a lot of flight sim. They gave me the trans-Atlantic route. You had to do the whole thing in real time, so I would take off, hit cruising altitude, lock the auto-pilot, then go to bed. I woke up late one morning, and my bird had gone down in a field outside Brussels, after running out of fuel. I quit shortly thereafter, when I realised I am a complete loser, and virtual airlines are teh lame.
