It really makes you realize just how far we've come in the last 60 years. In the 1950s homosexuality was considered a mental illness and the stuff of sexual predators looking for young boys... vs now where gay men and women are getting married, adopting kids, seeking equal rights. In some cases they're even running for political office.
If you're interested in finding more "sex education" or funny outdated videos on YouTube there are plenty of them.
What is REALLY funny is how some people (ie. Sarah Palin, Stephen Harper and similar politicians from the ultra-conservative Christian right wing) still believe in some of the outdated nonsense from that era.
