I went to two stores and could not find a single *normal* toothbrush.
It appears that no toothbrush available today has any two bristles the
same length or pointing in the same direction. They have racing
stripes, rubber fingers, "ergonomic" contortions, automatic carpet
height adjustment, all-wheel drive, parts that spin, parts that jiggle,
parts that play music, parts that light up, and the latest wireless
technology. They look ready to take on space travel or the dangers of
the deepest jungle. Even after gyros, I don't present a toothbrush with
that much peril.
