A man in Canberra decides the way to make a fortune is to open a ten-pin bowling alley. He builds the ultimate bowling alley with 20 lanes, 2 restaurants and various bars.
On the afternoon before the official opening he is standing around admiring his creation when he realises he's forgotten to order bowling balls. He rings the manufacturer in Sydney and orders 1000 balls. The supplier advises that he has them in stock and all he has to do is drill and polish them and then he can air-freight them to Canberra. The bowling alley proprietor says this will cost too much in freight and asks that they be sent by road in a 22-wheeler semi-trailer.
The supplier works into the night and the balls are loaded and despatched.
Travelling at great speed and in the middle of nowhere the truck driver sees two blokes standing on the side of the road. He stops to offer assistance and the two guys, who he sees are Aborigines. They tell him that their bike has broken down on the way to Canberra and they are stranded.
He offers them a lift but says they must travel in the back because company policy prevents passengers in the cabin. They climb in with their bike and he speeds off.
Shortly after he's pulled up by the police.
One policeman says to his mate, "You book him while I check his load."
He opens the back but quickly slams and locks the door. And he runs to his mate and says, "Forget booking him. Let's just get him across the border and out of New South Wales."
Despite his mates' protests, they head off at great speed to the Canberra border, escorting the truck. At the border they stop and the truck hurtles on.
The policeman then says to his mate, "Will you tell me why I couldn't book him and we had to escort him here?"
He replies, "When I opened the back I could see it was full of Abo eggs. We had to get them out of the state because two have already hatched and one of them had stolen a bike!"
