A spheroid pulled at the poles
—a pointedly comedic effect—
can wobble or flip when thrown,
or easily slip from the grip,
and the angle of bounce is unknown.
But keep these features in check,
and spiral this prolated shape
of dimpled pigskin when letting it rip:
then lo the rotational ellipse
arcs through the sky with grace:
zen of quadric face.
