Now seeing the show with the eyes of an adult feels like a portrait of a much simpler but much poorer era. El Chavo (mexican slang for "the kid") was a boy who slept inside a barrel in the shared patio of a slum ("la vecindad") where most of the action happens. With plenty of physical humor, El Chavo was frequently hit in the head as a punishment in the show, specially by Don Ramón, a character which would never find a job and was always hiding from the landlord.
It's the kind of show it would never pass if it were to be filmed on this date, but we grew up watching it and learning to love it, in the same way we loved racist cartoons by the Warner Bros. or those old episodes where the Flintstones were heavy smokers.
