Prince Charles turned 67 Saturday, but he and wife Camilla didn't celebrate his birthday weekend in Britain. They were still Down Under for the royal family's two-week tour of Australia.

There were, of course, serious duties to attend to over the weekend, such viewing the State Buildings:

But it wasn't all serious business.

Before the couple left, they were presented with a pair of boomerangs at Perth's Kings Park.

While they were sure to appreciate the historical significance of the weapons once commonly used for hunting by Indigenous Australians, they also seemed amused by the sight of each other wielding them.

The prince, in particular, found it entertaining — he even appeared to take a mock whack at the Duchess of Cornwall.

She smiled on and looked ready to return the gesture.

No word on whether they brought the objects back to Britain!
