I call them "Ally McBeal" moments. They could also be titled "JD from Scrubs" moments, those times where you drift off into active fantasy while operating heavy machinery or going about your day. As I was walking back to my desk just now, with my stupidly large Mocha Frappuccino, I had one where I wake up one morning to find my pancreas sitting outside my body on my belly. He's animate, has a little face, arms, and legs. He sees I'm awake, stands up, says "well, I warned you," and walks away in a huff.
Yeah, definitely time to start eating better.
