[5] In his previous film however, En un burro tres baturros, Infante was cast as an extra but collaborated by singing in place of Carlos López Moctezuma.
Before going in to dinner, Jesusita overhears Felipe tell Teresa and Tula that she should've been born a man because of the way she acts, but also says he envies her for her strength of character.
Jesusita appears at the window and asks if he'll play a song for her, but Valentín tells her that he won't because she has the heart of a man, and the men all laugh.
Valentín crashes the party and sings to Teresa while Jesusita clings to Felipe's arm.
The next day Felipe tells Jesusita he plans to marry Teresa, and she runs out of the room.
Felipe arrives to rescue Teresa and shoots Valentín with blanks that Jesusita has loaded in his gun.
Valentín then reveals the ruse and tells Felipe that Jesusita is in love with him, which he didn't realize until then.
