How to keep roos away from cars?

Of course those whistles attract Roos ... What is wrong with you people?? Are none of you Australian?? Did you grow up in a cave???

I mean seriously, how do you think Sonny got Skippy to come back to him all the time? It was the first thing that happened in the opening credits ... phwooo wit wooo .... and along came Skip to let him know there was trouble afoot at Blind Mans Bluff!!!!

ROFLMFAO!!!!!!!

So that leads me to think a Panel Beater invented those whistles then. One way to create work.
