Who doesn't flip for the royal wedding?

Kate Middleton took center stage at Friday's royal wedding, but one excited priest stole a little piece of the spotlight. 

In a hilarious video posted on Westminister Abbey's official Twitter page, a clergyman -- dressed in a black gown and priest's collar -- does cartwheels down the aisle of the church after Prince William and Middleton say, "I will!"

An amused Abbey rep tells Us Weekly: "Clearly he was very pleased the service had gone well and according to plan. He was expressing his joy and happiness."
