Ha ! Saverio ! ovvero Pulcinella creduto medico chirurgo, sposo americano e marito spagnola (Oh! Saverio! or Pulcinella mistaken for a doctor and a surgeon, an American spouse and a Spanish husband) is an adaptation for glove-puppets of a play written for human actors by Francesco Ferrajolo. Among the plays that Fransceco Ferrajolo acted in, for he was both an actor and a puppeteer just like his father Pasquale, there are several adaptations of texts from the dialectal theatre, sometimes from well-known authors such as Antonio Petito or Eduardo Scarpetta. Often, more than two characters are simultaneously on stage. For those shows, several puppeteers share a glove-puppet booth, one large enough to accommodate them all.

As is the case in other plays of the Ferrajolo family, Pulcinella is accompanied by Felice. Felice Schiosciammocca, a character who has become famous thanks to the actor and playwright Eduardo Scarpetta, is a representative of the polite society of Naples. In the plays of the Ferrajolo family, Felice is a friend of Pulcinella and serves as a foil for him. He is a cultivated person who speaks Neapolitan with an accent characteristic of the middle-class and the aristocracy.

The owner of a hotel is facing difficulties because she has been without servants for several days and one of her guests is very sick. Don Procopio and Don Enrico arrive at the hotel. Don Enrico would like to marry Don Procopio’s daughter. But Don Procopio has promised her to an American who is to arrive that very day. Pulcinella comes to the hotel and asks to be hired as a servant, but the old owner mistakes him for a doctor and Pulcinella finds himself forced to care for the sick man. Then, Marietta arrives, followed by Felice, who is courting her frantically. In order to get rid of Felice, Marietta tells him that she is married to a very jealous Spanish man. When Pulcinella arrives, Felice believes that he is Marietta’s husband and challenges him to a duel. While Felice has gone to fetch weapons for the duel, Don Enrico arrives and wants to kill Pulcinella as well, because he thinks that he is the American spouse of his beloved. At the end of the play, all the characters meet on stage and great confusion ensues.
