Fra i due litiganti il terzo gode (While Two Dispute, the Third Enjoys) is a dramma giocoso in two acts by Giuseppe Sarti.

One aria from this opera, "Come un agnello", is famously quoted by Mozart at the end of Don Giovanni.

[2] It became very successful, being produced under different names, in different languages, and in numerous European cities.

For instance, it was performed as Le nozze di Dorina, with inserted arias by Giovanni Battista Viotti, for the opening of the Théâtre de Monsieur in Paris on 6 January 1791.

The opera has a story similar to Mozart's Le nozze di Figaro (1786) involving complex intrigues between a pair of jealous, quarrelling aristocrats and their servants.
