Prince Charles is tapped out and shook up

After two weeks on the other side of the world, cameras and people in your face every day, travelling almost non-stop ... what better way to unwind than a quick two-step?

Charles and Camilla spent their last hours in Christchurch, New Zealand,  seeing both the highs and the lows of a populace that is still trying to recover from last year's earthquake that took 180 lives and shattered the rebuilding efforts that had been going on since a previous quake had hit six months earlier.

Just to keep their sanity, the locals decided one way to keep some level of fun in their lives was to have a public dance floor outside in a shopping area.

That's where Charles and Camilla found themselves after visiting nearby quake-stricken businesses. University student Sam Johnson was the first to approach the Duchess, asking for a dance as some Swing Era jazz filled the air.

A few quick twirls later, Camilla couldn't help but notice Charles was something of a wallflower. "Come on darling, you've got to dance, too."

That's when Lisa Shannon, 57, stepped up to the prince (because he looked "a bit lonely") and prompted an invitation to trip the light fantastic.

She and Charles put on quite a show, avoiding each other's toes even while cheek to cheek.

Hours later, the royals were on a plane, heading back to Britain after what most would term a highly successful tour of Papua New Guinea, Australia and New Zealand.
