Things you only notice about '60s cartoons as an adult
Television cartoons truly took off in the '60s, thanks mainly to Hanna-Barbera, the studio that made The Flintstones, The Jetsons, Yogi Bear, and a ton of other popular shows. Thanks to cable, home video, and streaming, even people who were born after the '60s have seen many of the cartoons of that decade, or remakes of the same properties. It's when you revisit them as adults, however, that you start to pick up on things that go unnoticed by kids of any era. These are some of the truly weird things only adults will notice about 1960s cartoons.
