Many things we grew up with seem weird today. The good thing is that we (the X gen) have a very natural relationship to our bodies. Beaches were 50% topless as well. We had very good sex education at school. We speak about sex with our children without special issues.

As for this show: try to sing the "tu tu tu tu" music of the closing credits, everyone 50-60 will immediately understand. If you want to show off your culture, you can mention the Canal+ movies on Saturday at midnight - the encoding was weird: you could not understand the sound, but with some experience you could watch the movie :)

Ahhhh, good times :) (as a 14 yo I learned quickly about electronics to be able to automate the TV switch off when the parents were coming too close)

NB: the link you provided is to the INA (Institut national de l'audiovisuel), the official national body for preservation of French TV and movies. It is a good thing they preserved that one - not for the nudes but to show that times were very different in the 80's
