It must be spring break...I don't log on for a day and then I have to read for nearly a half hour to catch up. I believe it's the "Pigeonhole principle." I wonder what the etymology of that one is...is it concerned with putting pigeons into holes, or with pigeonholing in the more abstract sense? Do pigeons even live in holes?

Oh, and what does "'midwest' in the east of the Mississippi sense" mean? I'm from the midwest, but not from east of the Mississippi.
