Flintstones

Did you know...
... that today is Prehistoric Family Day? The Flintstones, which premiered on this day in 1960, was the first TV cartoon show aimed at adults. Alan Reed, the original voice of Fred Flintstone, uttered the famous "yabba-dabba-doo" in the first episode. Originally, the line read "Yahoo," but Reed asked Joseph Barbera if he could change it to something with a little more "pop" to it... and the rest is history. Celebrate today by coming up with your own line that pops! ;-)
