XXVIII/2, is a short, two-act opera buffa by Joseph Haydn, the first one he wrote for Prince Esterhazy.

Based on the intermezzo from the third act of Niccolò Piccinni's opera L'Origille (1760), it lasts about 50 minutes.

Similar works include La serva padrona by Pergolesi and Pimpinone by Telemann.

In the end, the men recognize Gasparina's greed, but nonetheless willingly hand over their riches.

The comic potential is enhanced by Don Ettore being played as a Breeches role – that is, by a woman.
