It's a nice day for a... Flintstones wedding?!

British couple Ed Robinson and Gayle Watson went the Stone Age route for their nuptials, saying "I yabba dabba do" (literally) dressed as Fred and Wilma Flintstone, the Daily Mail reports.

While Robinson Bedrocked a black wig and orange leopard print toga, Watson walked down the aisle in a white and animal print one-shouldered dress and orange wig paired with a supersized "stone" choker, according to the paper. (How very Jeremy Scott of them.)

The dino-mite ceremony, held in Combe Martin, North Devon, England, also reportedly included a Barney Rubble best man, a Betty Rubble maid of honor, Pebbles and Bamm-Bamm child attendants and caveman-costumed guests, a Flintstones-style car (which we hope, staying true to character, they drove with their feet), and an inflatable giraffe as a Dino the dinosaur stand-in.

Probably by signing a stone tablet, the couple made it legal as "The Flintstones" theme song reportedly played.

"The Flintstones idea made sense because we both love fancy dress [costumes] and where we live in Combe Martin the scenery looks very prehistoric," the new Mrs. Robinson told the paper,

We wonder if the guests had a choice of chicken or brontosaurus burger.

Let's just hope she got a giant rock out of the whole thing... and we don't mean the kind that you find on the ground.
