In this corner... the charming McGuire Sisters.
And in this corner, the vivacious DeCastro Sisters!
As much as we love those "Sugartime" sweeties, we have to admit that, in this rumble, the DeCastro girls would not only take the McGuires, but probably bring back Phyllis' head as a battle trophy. You just know there were a few switchblades in those 'do's.
