Folks,
Forgive me for being silly, but even it I owned an electric toothbrush, I
can't imagine brushing my teeth in front of, or anywhere else near, the TV.

I'll bet the new list doesn't tackle hard-hitting questions like
this one!
:)
My understanding is that it (the digital clock jiggle) has something
to do
with the slight astigmatisms everyone has. But I couldn't begin to give a
source for that. I vaguely remember reading it somewhere.
I don't have cable, but as I understand it, there are more images
that
jiggle on some cable channels than on the regular tv. I'm going to guess
that's not what you're asking about, though.
