The episode of The West Wing that’s always bothered me is “Evidence of Things Not Seen,” which is Episode 20 of Season 4. It takes place on the day of the equinox (in March, not September, but I remembered it because today is an equinox), and one of the continuing subplots is C.J. trying to convince the others that you can stand an egg on its end at the exact moment of the equinox and only at that moment. Oh, and it has to be the vernal equinox, not the autumnal one.1
