Apparently kids need more "variety" today. That is one of the reasons why Fred Flintstone has been replaced by a professional wrestler on the Fruity Pebbles box. Although it is a "limited" run (only four million boxes), apparently John Cena is just the first of many people who will be gracing the brightly colored cereal's box.

If you don't follow WWE, this might seem totally random to you, so we'll elucidate a little for you. Dwayne "The Rock" Johnson started calling Cena "Fruity Pebbles" a while ago because of his penchant for brightly colored costumes, and also because it gave him the chance to call a man a "Yabba Dabba B****." Who doesn't want to do that?

After The Rock made that comment, WWE and Post (the cereal company) made an endorsement deal. And now Fred Flintstone's days are numbered. Is there anything The Rock can't do?

While we hold back our tears, remember Fred Flintstone's many years of service as the Fruity Pebbles spokesperson with some classic ads. Oh, Barney. Will you ever stop stealing Fred's Pebbles?
