NSFW?

Several years ago, when I was traveling someplace or other, I went into an airport bathroom stall and found... porn. It was not an event that I expected to be repeated, least of all at my place of work. But yesterday, I headed to the fourth-floor men's room, and what is on the floor in the last stall, in full-color, glossy format? Oh, yes, you guessed it: The 2006 "Images from the Hubble Space Telescope" calendar.
