South African Dutchman Van der Merwe, had never been out of South Africa. His first overseas trip was a holiday in Australia and he decided to spend an afternoon visiting Bondi Beach.

As he sat on the beach looking out to sea, he saw a long line of black dots out in the water and said to an Aussie who was sitting close by, "What are all those little black things out there?"

"They're buoys," said the Aussie.

"Boys?!" replied Van der Merwe. "What are they doing out there?"

"Holding up the shark net," the Aussie told him.

Bloody great country!" said Van der Merwe, deeply impressed, "We'd never get away with that at home!"

I work with a bloke called Van Der Merwe.  He's a forensic psychologist.
