"Vuelve a casa vuelve por Navidad" (come back home come back for Christmas), from which the episode takes its title, is the tag on the commercials for "El Almendro", a well-known nougat brand. An "Almendro" nougat bar can be clearly seen on a table at the end of the episode.
This Christmas Special is the first episode of the Spanish series that doesn't remake one from the original Argentinian version of Los simuladores (2002)
