It was huge in latin america. Maybe "El Chavo Del Ocho" is a bigger thing in Brazil than Mexico.
Everyone my age (30) has good memories of this series and will consider watching it again if its on TV. It was huge like Sesame Street is on the US.
As a kid, I never noticed that the actors were adults playing children.
Some episode with english subtitles: https://www.youtube.com/watch?v=fwm3MmWjess
(To brazilians, the version dubbed in portuguese is considered the better version).
I love to hear about the customs of other countries regarding this small, everyday stuff. Like how finns leave their babies in the outdoors: http://www.bbc.co.uk/news/magazine-21537988
I wish this was easier. Mostly I can be exposed to US and UK cultures. The other countries, only stereotypes.
