Roberto Gómez Bolaños was the show’s main creator and star. He called Florinda Meza to act in the show first; Chespirito and Meza later married. Édgar Vivar was the second actor chosen for the show. Roberto Gómez Bolaños recruited Ramón Valdés because he had known Valdés for years and had seen multiple movies Valdés had made. Then, Rubén Aguirre was cast in the show as the character of “Profesor Jirafales”. Aguirre and Roberto Gómez Bolaños had been working on scripts together for years, and Aguirre had already been playing the character of Professor Jirafales on another Chespirito show, Supergenios de la Mesa Cuadrada, which spoofed current events panel discussion. Carlos Villagrán just happened to be a friend of Aguirre who was a newspaper reporter, and he went to a party hosted by Aguirre. Villagrán did a comedy step where he blew his cheeks out of proportion, and Aguirre told Roberto Gómez Bolaños about his friend’s hidden talent. Villagrán was promptly hired for the show. María Antonieta de las Nieves was a voice-over only actress who used to go to Televisa to make announcements. Upon hearing her voice, Roberto Gómez Bolaños thought she was perfect for the show (she first refused telling him she was not a comedy actress, but Roberto Gómez Bolaños’s retort challenged her: “Then you’re not a good actress: there are no dramatic or comic actors—there are only actors. “). The last additions to the show were Angelines Fernández, a former film actress and Horacio Gómez Bolaños, Roberto’s younger brother who had never considered acting before; he was originally to oversee the show’s marketing.
