Ahead of Friday's big wedding, royal watchers feared that the new Duchess of Cambridge's wild uncle on her mother's side might cause some embarrassment for the Middleton family on the big day.

But while there have been no reports that Gary Goldsmith -- Carole Middleton's brother who lives in a house in Ibiza with the classy name La Maison de Bang Bang -- was on anything other than his best behaviour, some lesser lights did set out to try to steal the spotlight.

One of the 5,000 police officers on hand decided that with hundreds of security and media cameras on him, he would grab his five minutes of fame with a Charlie Chaplin routine.

The policeman's slapstick act included pretending to trip and stumble as he walked down a cleared roadway, eliciting oohs and ahs from the spectators waiting for a glimpse of the newlyweds, and waving his arms to entice cheers like a mascot at a football game.

In a wild moment that took place closer to the royal couple, a rider-less horse broke away from its formation behind the carriage taking the newlyweds to Buckingham Palace, and galloped down the Mall.

The horse continued on past the carriage and down another cleared roadway, sending dozens of policemen scattering in all directions to avoid being trampled.

And in a moment hidden from the public's view, but not the all-seeing eye of YouTube, a verger decided to have some post-wedding fun inside Westminster Abbey after the guests had gone, but before the cameras had been turned off.

The verger, identified by the British media as Ben Sheward, can be seen walking up the Abbey's centre aisle when he inexplicably decides to practice his gymnastics.

As he saunters up the red carpet he turns not one but two cartwheels. He then continues skipping up the aisle with a big grin on his face, until he disappears from view. A verger is a layperson who helps the clergy prepare for, and assists during, a service.

A spokesperson for the Abbey defended the verger's actions to Britain's Daily Telegraph newspaper.

"Our view is that the verger was simply reflecting what we all feel about a very successful service. It is a general reflection of the mood of the Abbey and a job well done. It was long after the congregation had departed and we were all reflecting on what we had achieved."
