Bert and Benny bought a ring
for their girlfriend Freda Fling.
She would date Bert on the day
that the other was away.
And when Bert was out of town,
Benny would come hang around.
They decided it was fair
to approach her as a pair,
and suggest a marriage of
brother, wife, and brother love.
Freda gave a moment's thought
to the coupling that was sought.
Turned them down with no regrets,
and left to marry trip-o-lets.
