For this, we need you to use your imagination. Sir David Attenborough is standing behind a tree in Terry Lamb Reserve on Monday night, binoculars in hand.

"In the Antipodes, there is an ancient, isolated tribe," he whispers, so as not to scare the local fauna. "The tribesman will often express camaraderie by touching each other's nether regions. They have been known to greet each other by pinching their fellow tribesman's penis."

As he moves closer to Belmore Sports Ground, he is stopped at the gate. He has the wrong coloured media pass.

The NRL has warned over the past 12 months Newcastle's Korbin Sims and Canterbury's Josh Reynolds for touching friends in the opposing team "below the belt" during matches.
