Fred, Wilma, Barney and Betty first showed up on this day on Sept. 30, 1960. Making it 50 years old yesterday. The half hour Thursday night show started in 1963. This was probably Hanna-Babara's finest hour, as later efforts were eclipsed by The Flintstones. It's very funny and very touching. I cried when I first saw this as a little kid.
Here's an episode I particularly like on YouTube. It's how Bamm Bamm became a Rubble.
