Maggie and Jiggs are back in “Of Cabbages and Kings,” an extravanga that contains dailies and Sundays from 1937 and 1938. The combustible-yet-inseparable couple go to London for the King’s coronation. Upon their return, Jiggs decides the only way he’ll convince Maggie to move back to the old neighborhood is to lose his fortune. He makes the one outlandish investment after another but each time he only becomes richer. Until he hits on the right formula. For Maggie, the unthinkable happens: it’s back to eating boiled cabbage when the wealthy Jiggs goes broke!
