Egg on My Face

It's no secret that I am not a scientist...I believe I made that perfectly clear. Now, Dave comes out of the woodwork to emphasize that fact emphatically, and destroying precious memories for my children as well. I only hope they don't hear about it because they'd be in therapy for years.
I do find it hard to believe that we managed to pick the EXACT time on various days to perform the "eggsperiment" with the chicken ovum, but Dave says we could have done it any time. I am going to begin tomorrow and try every hour of every day for, oh, a day or so just to see if he is right.
I think this is how the government tricks us all the time, too; they take perfectly good photographic evidence of, let's say, a spaceman flying over the desert or an actual corpse of one (or an egg standing on end) and have some egghead give us a lot of scientific jargon until we are convinced that what we saw was a result of those mushrooms we'd been eating. Anyway, what follows is the transcript of he missive from Dave (if that's his real name and not a government-given undercover moniker)regarding my previously reported story concerning the equinox and eggs:

DP-
I hate to disprove your family tradition of standing an egg at the equinoxes, but this in fact is only a coincidence and can be done on any day of the year.

There are definite gravity variations on the earth; most often a function of latitude and vary only by about 1%.

The equinoxes present nothing special as far as gravitational forces are concerned in our universe. Remember, earth's orbit is elliptical: perihelion and aphelion then should also disrupt earth's gravity, but yet it still doesn't vary by 1%.

Even if this "balance of gravity" occurred at the equinoxes, it would have to be done exactly at the correct time when the sun passed over the equator's zenith. The equinox doesn't last throughout the day, but only at that exact moment. Otherwise, there's already a "variation." Accordingly, latitude also would become a factor as the sun is not directly overhead everywhere on earth.
