Happy 50th anniversary, Fred and Wilma

On Sept. 30, 1960, "The Flintstones" -- a modern stone-age family -- debuted on ABC. It became the longest-running animated series when it finished on April 1, 1966, a record which stood until being shattered by "The Simpsons."

So tonight, Fred and Wilma Flintstone, along with their neighbors, Betty and Barney Rubble, are celebrating their 50th anniversary.

Yabba, dabba, doo!
