It's one of the greatest theme songs in television history — certainly one of the catchiest. Fair warning: It's about to be stuck in your head for hours. 

Perhaps what's most surprising about "Meet the Flintstones" is how long it took to come along. The song is forever associated with the cartoon series, but it was not used until the third season. Before then, an instrumental called "Rise and Shine" was used. We bet you recognize that melody, too.

As soon as "Meet the Flintstones" was introduced, it became an immediate hit. You've heard it countless times over the years.

So let's see how well you remember the lyrics! We're talking about the entire song — including the second verse used in the closing credits!
